Yes, I hadn't even considered that such a prominent class would have 
this problem ;)

Quite.  By the absence of many responses to this RFC, I take it that 
there are no strong objections to the proposal.  Likewise, there 
hasn't been much talk in support of it.  I take it from the silence 
of the list that there is indeed a problem that this RFC addresses, 
but is only sufficient to fix the problem, and not necessary.
