It returns what it always did: a real with value 0.

The new API that is introduced in Qt 6.7 as it stands now just makes 
that value act as the /default/ value for the more specific radii 
properties. I think that that is sound design: it's backwards compatible 
and consistent with things like anchors.margins providing the default 
for the more specific margins (except for the fact that that property is 
spelled margins (plural) while radius is singular.)

Anyway, I think that this is besides the point. The point I wanted to 
raise was that having four separate properties isn't ideal, and that we 
could give ourselves a lot of room for improvement by having a `corners` 
grouped property that can contain more than just a single real value for 
a radius.
