Seems a bit odd to blacklist a mod made specifically for a single server, especially for the listed reason. I completed pelagos (researched pelagos-specific infinite techs up to 400k in cost) in my own "every planet mod at once" run without engaging with the ships at all beyond trigger techs (had enough other mods to just use pipes for the offshore oil rigs), and the other additions/production chains stand just fine on their own, especially the landfill productivity tech also boosting foundation and overgrowth soil.

1. Restore vanilla Cargo Ships recipes & technology (removing Planet Pelagos changes)

That is the reason.
I was basing on changes listed in description. After reading that I was pissed off and did not even bothered to open mod.
Because mod lacked proper changelog I assumed that is list of changes it introduces

There is a lot that can be removed from planet and it still makes sense, but that is one thing that can't be removed.
Core role of planet is to be place where you unlock ships.
Without it, it's existance is fundamentally pointless, and I don't want to see my mod beeing just hollow husk. I would rather wish it's not used at all

I can understand not wanting to see your vision for your mod's core feature removed or reverted, but at face value it comes off as a bit petty, and in the end there's not much you can do about people making addons (public or otherwise) to change your mod to their liking, or forking the whole thing for the same purpose, maintaining their changes alongside feature parity with your version. A notable, similar example from the vanilla game was when they made landmines blow holes in space platforms, several mods came out reverting the change just hours later.

Its not tweaking to liking or fixing exploit like you said with landmines.
Its removing reason this mod exist in first place.

Planet was made in a way it should be easy enough to throw in and out in existing save keeping ships, and few other things as well, and I am slowly working on dissasembling planet features into separate mods, so you could reasseble pieces into something else, use it with SE etc. But that is difficult and takes time to make

There is one part of this planet that you can't remove and expect it to still make sense. And that is what blacklisted mod did, and published changes so other people could expearience this hollow husk as well.

I am saying it again. If you want to remove its core purpose there is no reason to install it.
I am trying to build it in a way it can be easy to do so, and you can expect having ability to keep more stuff if you remove planet in future.
About month in total was spend on making this planet starting one as well. And its much more changes tweaks and balancing stuff then most planet start mods do. To have some choice if you like planet but also want to have ships from get go. That is the way to do it that don't throw its fundamental design into garbage.

My changes to cargo ship power, diesel machines, lighthouses etc. That is stuff that could function in healthy way standalone. They will eventually be separated

Things like cargo crates or example in making water enemies are already separate mods.
I also recently made core libraries for liquid fuel and my cargo ship changes.

If someone don't like my idea for what this planet then it is completly fine.
Unless you try to make abomination from it, and publish it for me to see it.

I don't want to see it. I want other mods to respect my work as I try to respect theirs, by trying my best to preserve what they are, and directly helping creators

Thats all I have to say
If you feel need to talk some more finding me should be easy. But I am not sure what more I could say
Have a nice day
