This was asked explicitly on irc #wayland last Monday (iirc) by SardemFF7.

This is not to distinguish from a "real" min/max size, this is intended to make it very clear even in the request name that this is by no mean enforceable by the client.

In other words, it's just a hint (just that we can't use hint as this is dirty word nowadays ^_~)

I reckon this is the compositor implementation, not sure this should be in the spec.

Cheers,
