It would be awesome if there was a signal I could send to convert a stringy train stop into a regular train stop. I only need to name stops at outposts once, after that I never rename them or send any type of other stringy train stop signals. Only the one stringy train station that configures newly built trains is actually used several times. So I don't want a migration that just converts all stringy train stops once. I only want the ones receiving the signal to be made into vanilla train stops, and I want to be able to do it at any time. Obviously a vanilla train stop wont be able to be converted back to stringy train stops with a signal, but that is ok, I want a permanent conversion.
With potentially hundreds of stringy train stops that just waste CPU cycles running Lua every tick it could become a performance problem.
Also if I remove the mod then all the stringy train stops are removed as well and my base stops functioning, despite the base actually being otherwise completely vanilla. I only use mods to place blueprints and configure things with circuit network, after that the base itself should work without the mods.
The Crafting Combinator adds an extra entity that can be used to configure the recipes in vanilla assemblers (and other entities with recipes) next to it. This entity can then be removed and the vanilla assembler entity keeps its configuration, achieving the same goal of only needing the modded entities when building but not when running the factory.
