Calling `tramp-crypt-add-directory' interactively is the only way to
activate package tramp-crypt.el. As long as the package isn't loaded
yet, this command must be visible.

No, because otherwise tramp-crypt.el would be loaded unconditionally due
to the command completion of `tramp-crypt-enabled-p'.

Yes.

I have adapted tramp-crypt.el such a way, that `completion-predicate'
for `tramp-crypt-add-directory' is set only after loading tramp-crypt.el.
