The ideal case for me is that I don’t need HACS at all. My experience has been the same - I’ve happily been able to switch to core HA components and stop using HACS ones. It’s great to see HA is not idle with success, they are continuing to make new features even when backwards compatibility may break.
Every time I try to do the same thing I just end up renewing my Sublime. I’ve spent hours configuring and trying other editors and I just can’t do it in the end - Sublime is so fast, productive, bloat-free, and perfect. I’ll be watching this though for next time, because I know I’ll try again at some point. Good luck!
