ecase comes from here:

   commit fcd737693e8e320acd70f91ec8e0728563244805
   Author: Richard M. Stallman <rms@gnu.org>
   Date:   Fri Jul 30 20:15:09 1993 +0000

       entered into RCS

renamed to cl-ecase here:

   commit 7c1898a7b93053cd0431f46f02d82c0a31bfb8bf
   Author: Stefan Monnier <monnier@iro.umontreal.ca>
   Date:   Sun Jun 3 21:05:17 2012 -0400

pcase comes from here:

   commit d02c9bcd096c44b4e3d5e2834c75967b56cdecdd
   Author: Stefan Monnier <monnier@iro.umontreal.ca>
   Date:   Tue Aug 10 15:18:14 2010 +0200

       * lisp/emacs-lisp/pcase.el: New file.

Not very nice to dismiss other peoples preferences as "just your
personal preference" while pushing through your personal preference.
That ecase macro was there for many decades, even before import to RCS
and you broke it and force your pcase way on everybody.  The author used
pcase because of you, not very good argument for pcase merit.
