It's not a matter of "tolerance for risk", it's a "if this change is
good enough for future releases, why isn't it good enough for older
releases as well?"

As you know, we don't break user interfaces, so either this is a break
or it isn't, stable trees have nothing to do with it as a normal user
would "hit" this when updating to run Linus's tree, just as easily as
they would "hit" it updating their stable kernel version.
