I don't see the justification for this, sorry.  An id is just an id, it
doesn't matter what is is and nothing should be relying on it to be the
same across reboots or anywhere else.  The only requirement is that it
be unique at this point in time in the system.

We're having this same discussion on a different thread for a different
bus as well.  This isn't something new, it's been hashed out and
resolved 20+ years ago...

So no, this change isn't ok to make at this point in time, sorry.
