My issue with GHA and other "dead simple" systems is that my CI is complicated. Having a real programming language for stuff like "calculate what date it was a week ago" or "concatenate these three strings but only under some conditions" or "parse the output and build an object out of it" is really helpful while a bastardised YAML-based Jinja template simply can't hold up.
But yeah, if all there is to do is "git clone && build && deploy" then Jenkins is an overkill and it probably wasn't warranted in the first place.
