It would mean stopping any changes that would modify the representation,
yes.  I think there's still a fair amount of development that can be done
within those constraints, but it is certainly a significant limitation.

Somewhat, as we wouldn't have to worry about the template code having been
compiled into all of the users' .o's.  But it isn't implemented, so it's
moot.
