Only in the old spec which is replaced by the new which doesn't say.

And since the old spec doesn't give a clue as to why 31 bits vs 32
or even vs only 8, I'm looking for a concensus to make the pronouncement
"official".

FWIW: I believe that in most cases its isn't going to matter.
And in the bidir interop problem I found, there are some fairly
obvious work-arounds.  But in the end, it would be better if
we all agreed.

When the new PIM-SM replaces 2362, it is kind of harsh to expect
new implementations to comply with an obsolete spec.
