I also like it, and your assumption could be true.  Who knows.

Pcase was a big improvement to what can be expressed with Elisp.  And I
think its syntax and semantics are quite straightforward.  I doubt we
will find something more simplistic that has the same power.

Probably the main problem was that the documentation was originally
written in a quite terse academic style.  Also, the recursive nature of
` that makes it possible to combine it with all other patter types is
hard to get, but also very natural and powerful.  It's just consistent
that when backquote is used to construct complicated lists, it is also
used to build complex patterns to match such lists.  Nonetheless it
seems that ` is one of the main reasons for the bad feelings some people
have about pcase.
