Both split responsibilities based between on what is the "real config" or "helpers" with macros/functions, but the thing is doom-like-style puts it all in one folder(example: /ui/modeline/config /ui/modeline/utils) while other split in two (lisp/lisp-modeline.el, modules/my-mod-modeline.el), and would like to know your opinion about this and what worked for you.

Some context: By now all my settings are all in one init file, and it already passed the 2k lines mark and once something break, everything breaks, so this is needed to avoid future headaches
