Ah yes, I have almost zero experience, apart from using one. (I did play with
Android Studio a bit, but mainly to learn a bit about Android, nothing
serious.)

This is a nice idea, but I'm cautious because I suspect there are people out
there who already rename or alias pcre2grep as grep, and I'd rather not break
their worlds. How about this compromise:
Implement -E, -G, and -P as suggested, and also do my original idea of a
build-time option for selecting which is the default. Then recommend very
strongly that if the default is not -P, the program should not be installed as
pcre2grep, but as something else, e.g. grep. I could live with that.
