I agree with you. I didn't actually advocate the minimalist version;
I just wanted to point out that we need a BCP in any case.
So, I suggest something like this:
OLD:
If ISOC further modifies [ISOC-By-Laws] concerning the number of IAB
appointments to the ISOC Board or the timing thereof, the IAB will
make reasonable modifications to the processes embodied in this
document, without requiring further modification to this document.
Such changes will be announced via an IAB statement.
NEW:
If ISOC further modifies [ISOC-By-Laws] concerning the number of IETF
appointments to the ISOC Board or the timing thereof, the IAB may
make corresponding modifications to the frequency and the timing of
the processes embodied in this document, pending any modification to
this document. Such changes will be announced via an IAB statement.
I think a change such as that would be good.
