Of course. And those are the "hoops" that need be jumped,
and have absolutely nothing to do with Emacs's coding practices
or culture, they're just plain old engineering challenges.  If one
has little time or is bored to solve them, it's easy to flee to
MELPA: a fresh start, no-one depends on the new package,
which usually has a user base of one (or close to it).
