It may or may not be undesirable -- we have no data other than your
original message indicating that it is.  There have been no proposals,
no code contributions, and nothing other than anecdotes to demonstrate
that "many people" view it as a problem.

I interpret this lack of discussion as an indication of priority.  I do
not consider this a priority, and have not to this point, and I have only
looked at it briefly.
