Ya the snapper / snapshot / limine default behaviours seem to require more space than a typical boot loader config, even more so if you are doing dual booting and another distro has also put something in /boot
Probably best to take the discussion to an existing thread
On the original topic however not much is hard to change moving forward other than the partitioning and even that isn’t too bad if you are careful.
Edit: the next release has happened.. Limine is the default boot loader and plasma is now the default login manager.
