Merges requests within a repository

[John]

Is there a reason that merge requests within a single repository are
not currently supported in the Gitorious ui? For example if I have
write access to a repository of which I have not created a clone of I
would like to be able to just create a branch within that repository,
make some commits to it, and then have those commits reviewed before
they are merged back to master.

I do realize that I can make a personal clone of the repository and
create the merge request that way. But when working on a team where
multiple committers want to be able to push/share a single branch it
is easier to keep the code in a shared repository.
