i don't have a particular opinion about #1 or #1 so please
do what you feel is best.  #3 should be done.  hopefully
they will accept reverting this change, or at least finding
a different solution...

please feel free to commit this support to our xsrc!

i am not sure who your hesitation came from, but i certainly
want xsrc to continue to support our older platforms and
very much appreciate your continued work here.  i will keep
merging changes forward as best i can when updating our xsrc
components.

thanks.
