OTOH one could build distrib similar to spacemacs/lazyvim, then you could just start with that, and once you find one particular plugin annoying or lacking, you could swap it for something else, at least theoretically (I've never used those personally, so I don't know how hard it is in practive). Not so much with all the eclipses and jetbranses of the world.
