I think that it's about not "cluttering" the global namespace with the
parameters. Zplugin had 37 global parameters, now it has only 16. Even
a situation when a curious user enters print $ZPLG<TAB> and sees fewer
entries is positive. This hides implementation, on the other hand, but
one can decide what to hide when writing, i.e. what isn't meaningful
for a curious user.

PS. The message should go to zsh-users, hence I'm moving it there.
