The same can be said for new shells that have popped up in the last 5-10 years versus bash. They're not sufficient to escape the local minima of 'good enough'.
I wonder what things you use that aren't specified by POSIX.
I've spent many years of my career crafting tooling to sync dot files and binaries around and largely over time just gave up on it as the juice is just not worth the squeeze.
I interact with multiple Unix systems daily too. Some of those systems have ripgrep and some don't. Unless I'm in a particular scenario where I think ripgrep would be useful, I just use grep instead. I don't really see the issue. For a short-lived machine, yeah, I don't bother with syncing dotfiles and all that other nonsense. I just use the bare OS environment and install stuff as needed. But I also have plenty of longer lived Unix machines (like the laptop I'm typing on) where it makes sense to set up a cozy dev environment optimized for my own patterns.
Sure, I get it. You don't work in a company that has this sort of culture, but a large number of us do. And you want us to. Do you want AWS engineers being able to just install whatever they want on the hosts running your VMs? Of course not.
