You're missing the point.  pcase has flaws, and even now, 14 years
later, isn't satisfactorally documented.  All you seem to be saying is
that pcase is better than no pcase.  I'd agree with that.

But if pcase were so good, why is Richard writing a better replacement?

You're being a bit vague there, but when have all active contributors to
any area of code been in agreement?

That's not the way things happened.  pcase was simply installed in
Emacs, with all its faults, and then proliferated round Emacs.  Where
was the room for discussion?  Discussion is difficult after something
has already been done.

If you're trying to say that pcase is better than nothing, so people use
it, then I'd agree.  But if you're trying to insist it's as good as it
could be, I'd ask you why Richard is spending a lot of time crafting a
better replacement.
