I do not have a strong opinion on whether it is a good idea to make
it possible to remove the .git/modules/*, but should it be a
separate subcommand, or should it be an option to the 'deinit'
subcommand?

Also, how would you apply the safety to a repository without
"upstream", i.e. the authoritative copy?
