How to deal with reviews in mentors.debian.net and repositories for new packaging work

[Emmanuel Kasper <emmanuel@libera.cc>]

I have uploaded a package on mentors.debian.net, and I got some review
of my package suggesting some modifications
(http://mentors.debian.net/package/vmtouch)

Now that I have done the suggested changes, should I rather:
A) delete the old package, upload a new one with same version number
(and lose the reviewing suggestions)

B) keep the old package online, upload a new one with same version
number (at the expense of some confusion in the mentors.debian.net page)

C) delete the old package, upload a new one with a new revision number
(even if the changes are minimal)

I have also read on the list that some mentors like to have a link to a
VCS to review the pacaking work. Is it possibile to host the packaging
work on alioth when you're not a Debian Developper ?

I know for instance NetBSD has an extra CVS repo called pkgsrc-wip where
all newbies can out their stuff before it's added to the real thing.
If not I can use github/gitorious.

Greetings
