Yeah, I'm in a similar boat to you. Unfortunately we're not the majority of the users in the Apple ecosystem, so our use cases aren't really what the design changes focus on.

The only changes I've noticed in the last few years are telnet, emacs, and ftp aren't included anymore and I have to install them manually. Changing to zsh was good though.

I wouldn't be surprised if they continue and eventually I find out that things like grep, awk, sed, uniq, etc are all slowly taken out.
