Bill, you again managed to drop people from CC. Please do not do that.

I really don't think we want to encode that into the protocol
specification. "Unset" is the right answer here.

The compositor can have its own preferences, and you can have your
100x100 limit there. Nothing says the compositor must use the minimum
hint size for initial size, and I expect most compositors will also not
do so.

Not exactly always.

And yes, like in my rephrased question, there is very definitely an
interaction, or you may see a size change glitch on opening new windows.


Thanks,
