Disclaimer here: I work for Rocket Software who offer lot of ported
tools for free. My opinions are my own!
REXX is great but it doesn't scale for writing large software solutions.
It doesn't have modules, variable scoping and all those things
we expect from modern languages. it's pervasive so we all use it. I use
it all the time for ISPF edit macros, USS scripts and all sorts
but when it comes to a serious software solution is just doesn't cut it.

I have found (from my co-workers especially) that most mainframe people
of a certain vintage are not willing to learn new stuff.
So regular expressions are off the menu when they can write logic to do
the same thing using their language of choice.
Of course, that's totally fine. Old dogs new tricks! RE does take some
learning but it's a case of "I can't be bothered".
I love regex, especially the PCRE. I also use z/OS Unix facilities in my
"normal" work. OTOH, my boss is one of the "don't want to bother with that"
types. Each to his own. Except that he really doesn't like me to use Unix
facilites in any of our "production" environments. The reason is "so that
the person coming after you can understand it". Which is weird given the
fact that UHG will kill the mainframe soon "come hell or high water". They
have enough money to do it too. Anyway, I end up writing a lot of REXX
instructions to do what I can do in just a couple of lines of awk or sed.
Even the "minimalistic" (anemic) versions of those that IBM distributes.
