It's not restrictions about what programmers should do in Emacs, it's
restrictions about how to structure an Elisp package: the file itself
should be "declarative", such that the `load' itself won't affect the
behavior of Emacs.
This is a convention that doesn't come from me, but has appeared over
the years as being useful. The example of `customize' is just one
of them. Another case where we load a file and don't expect it to
change the behavior of the running Emacs session is when you
byte-compile a file that requires `foo': the byte-compiler should be
free to load `foo' without having to worry about it changing the
background color of the running session.
Note also that it's a convention that most packages have always followed
without even thinking about it. And the few packages that didn't follow
it had no trouble adjusting.
