Perhaps take a look at yadm which can adapt dotfiles (via symlinks or esh-based templates) based on system attributes such as os or hostname

I just learned about stow, which as far as I understand, is a package that kinda manages the whole symlinking bit for you plus a few things? Honestly, I am not sure how it would differ exactly from what you’re doing, but you should check out a short video on it: https://www.youtube.com/watch?v=y6XCebnB9gs&t=3
