Does this patchset make it so that there are 3 states?

Active (unmerged head)
Inactive (completely merged)
Closed (explicitly marked closed, whether or not merged)

I would still like to see Inactive branches for some time after I have 
merged them into a different branch. Our current process is to merge 
right away to bring the changes into our tip version asap (for version 
branches, for features we leave them unmerged until complete). We could 
do what we are doing with clones, but it would be very inconvenient to 
have clones for each release (every time we need to switch to a new 
clone we need to modify IIS settings and locations for windows services).
