I think you could get away with defaulting the minimum to be about 
100x100. I think that is sufficient to get clients to work ok and it is 
small enough to encourage them to set this rather than relying on the 
default.

If the surface is currently smaller than the minimum it should act like 
the current size is the minimum.

These should have no effect. The client is free to supply sizes outside 
the range it claims. And the compositor is free to request them. It is 
only a hint.

Under ICCCM and some X window managers it was literally impossible to 
change the minimum size because they refused to set it smaller than the 
window, and would also refuse to set the window smaller than the 
minimum. That was very frustrating. Please don't do things like that.
