I'm generally adverse to granting feature freeze exceptions to code
refactoring: the user benefit of having them in the release is
inexistent, while they introduce some risk by changing deep code
relatively late in the cycle. That's why I prefer those to be targeted
to earlier development milestones, this avoids having to make hard calls
once all the work is done and almost completed.

That said, if the risk is under control and the patch is ready to merge,
I'm fine with this as long as there is some other benefits in having it
*in* the release rather than landed first thing in icehouse.

Would having it *in* the release facilitate stable/havana branch
maintenance, for example ?

Could you expand on why this would be a lot more helpful to have it in
the release rather than early in icehouse ?

And to have all cards on the table, how much sense would the alternative
make (i.e. not land this final patch while a lot of this feature code
has already been merged) ?
