is there any recommendation, which legacy library should be used? It seems, that the libs on Github, which are orphaned are not identical with the libs, which can be downloaded from KiCad’s official site.
To answer your question in the title: As long as you use a workflow where you can control which version you get, you should be ok. (Meaning: do not use the github plugin for footprint libs as this gives you no control.)
To be honest, I’ve used the zip download for the footprints, because it’s way more convenient, than to clone all .pretty repos separately.
On the other hand, I think using the latest symbols lib (v4, from Github) would be better, since it would be more complete, right? I would prefer to do that also with the footprints. Is there something like a super-repo for the footprints available?
