Thanks.  You're a long-time contributor in so many ways to the VM that I
know this won't prejudice the program committee against you.

Absolutely.  And it might help convince the program committee to invite
someone if they were seen to be active ... ;-)

The second is a little more involved with the rest of the patchset,

with the rest of the patchset.
