Sure. I was worried about throwing away other settings the user
might have set in the submodule.$name section and the first reflex
was to protect them. But thinking about that again I noticed we are
already throwing away a possibly user customized "url" setting, so
we already remove a possibly customized setting.
Maybe the principle of least surprise is better followed when we
nuke the whole section, as it might surprise the user more to have
a setting resurrected he customized in the last life cycle of the
submodule than seeing that after an deinit followed by an init all
former customizations are consistently gone. So I tend to think now
that removing the whole section would be the better solution here.
Opinions by other submodule users?
