In defface specs parameters like `min-width 10' are specified in the
condition part of `defface' like `min-colors 88' as a list.
For non-conditional parameters I agree that the plist syntax is better.
And defface spec merges plist attributes from inherited faces.

I also want to note that tags like `reuse-window' and `pop-up-window'
are redundant in plists.  Their meaning can be expressed as plists like
`:window same', `:window other', `:buffer same'.  This would bring
them closer to the syntax of defface specs that is proven to be flexible
and easy to configure.

It would be very sad to revert and move development backward.
