Yes, the idea is that at the end of the merge window -next should only
have a few fixes in it since everything should've been sent to Linus.
This also applies to things being added after you've sent your pulls to
the DRM core maintainers, if something isn't going to go in during the
merge window you shouldn't be adding it to -next.  

For the most part nobody's actually checking that other than the reports
I send to Linus highlighting which trees have the most commits in -next
so if you're not disruptive the chances are nobody will notice but you
shouldn't do it.  As Miguel says it's trying to avoid causing issues for
other people, plus the general concept of -next is that it's covering
what's currently scheduled to go into Linus' tree.

Of course, nothing stops you maintaining a branch which isn't in -next
and is open all the time and that won't have any wider impact.
