So I saw your comment about 2.0 maybe removing the need for this, and NO! It certainly does not. For a few reasons!
1) Quality sorting. As I have played more Space Age, I am finding that at least for my style, I would prefer to use bots to move quality ingredients around in a setup to "upcycle" (as in, feed in normal ingredients, get out legendary or epic products, of a specific thing) stuff. The problem is that if the networks are all overlapping, then one build is going to steal uncommon plates from a different build, and that will throw off ratios, etc.
So the point here is that having a separate network for each build makes this much more simple, as nothing will steal from anything.
Obviously you can "isolate" networks in vanilla, but the problem with this is that you have to space them out by a TON. and you cannot overlap. That's one of the things I love about this mod, is it lets you overlap separate bot networks, and you can have interaction between separate networks over a large area.
In this case, you could have quality upcycling builds RIGHT NEXT TO EACH OTHER, which are not going to share/mingle products/ingredients, which is exactly what you want.
2) modded roboports can be much MUCH larger than vanilla, providing even more value to having isolated networks, since you can't just easily "not connect" them. My example for this was actually when I used this mod in (i think) a bobs-angels-omni playthrough, and had city blocks, and I wanted each city block to have its own network, but not have bots flying between city blocks. But the problem is the modded roboports were so large, they would spill into adjacent city blocks with their radius. So I needed to use separate channels.
I am sure there are even more reasons that this mod is still needed. The simplest "family" of reasons is just that it provides a functionality (an isolated bot network that is "within" a larger bot network) that cannot be achieved with vanilla or SA. This functionality could have an endless list of use-cases, far more than I can think of above.
This being said, I understand maintaining mods can be not-fun or annoying, so if you are wanting to find a way to move on, I would simply ask that you put the mod up for adoption in the mod-making discord, and I'm hopeful that one of the other mod-makers out there would be happy to take on ownership and maintenance of it!
