thanks for posting the links.

my major point is that you have maximum flexibility when you can use
find, a tool designed for exactly this purpose, to recurse and filter
the fs tree, and grep to do what it is good at, which is, to use a
correct but ironic term, grepping.

xargs is insufficient partly because it cannot efficiently call shell
functions.  this is important for a variety of reasons including being
able to preprocess files.  preprocessing can include uncompressing,
unarchiving, and so on.  shell functions are useful for that.

imho, if there is a need for grep -r, then there is a need for pathname input.

find already has.  adding piped pathnames leverages that.

imho, allowing piped input reduces the need for debates on whether it
should or not.
