I unfortunately do not have your crystaline perfect recall. I used vi/m for nearly 20 years before drifting onto kakoune and now helix; I’ve been using them for about a year, and it’s getting harder and harder to not make reflexive mistakes when I’m trying to use vim. sed was already odd with regex escaping (parens but not brackets? Why??), and I know the less I use it the more I’ll forget. This is crippling when I have to work on a system that doesn’t have these new tools installed.
