I think it really depends on when you entered the ecosystem and the maturity of the integrations you're using. HA has some contribution standards but you can get plenty of "I made this in my freentime and upstreamed it" integrations that end up going through major renovations. Sometimes vendors take notice and also weigh in.

Additionally, if you got in ~5 years ago when it was pure yaml, it seems a couple times a year there's breaking changes where more yaml is ripped out and manual reconfig is necessary (it'd be nice if it just migrated the config for you)
