The title is perhaps underselling it: although it is a protocol extension (and hence a new feature) the main motivation is to fix a bug in hvmloader which causes HVM guests to hang during booting on a busy machine. The bug is fairly easy to reproduce with ~200 VMs: you’ll probably find at least one failed to boot.

I think a release exception is like an Acked-by or a Reviewed-by: it 
applies to a specific version of a patch series, not the general idea of 
the patch series.  There's no point arguing for a release exception 
until you actually have an otherwise fully-Acked patch series.
