Not usually, but there have been exceptions evaluated on a case by case basis.

I haven't looked at the patches, but in principle, I'd support it,
from the standpoint that since we're adding SVE support, might as well
add all of it.  Also, speaking with my Fedora/RHEL had on, we'd likely end
up backporting them too.  Can you give a guesstimate of the risk those
patches bring in to other ports?  I'd assume they'd be pretty self contained.

Well, the user manual, if there were any changes to it.  

If the SVE support included any new XML target description feature,
that should be mentioned in the manual.
