I am now convinved that back then I was very firmly wrong, and that staying out of the stdlib has been the best thing that could have happened to regex.  No doubt MRAB will disagree :)

I was, at one time, in favour of including it in the stdlib, but then I 
changed my mind. Being outside the stdlib _does_ give me more 
flexibility. I can, as you said, just get on with it.
I even have it on a Raspberry Pi. "pip install regex" is all it took. No 
need for it to be in the stdlib. :-)
