As the ELisp manual says, faces do not override each other, they are
merged:
The priority matters when two or more overlays cover the same
character and both specify the same property; the one whose
‘priority’ value is larger overrides the other. For the ‘face’
property, the higher priority overlay’s value does not completely
override the other value; instead, its face attributes override the
face attributes of the lower priority ‘face’ property.
IOW, only the same attributes in the lower-priority overlay's face are
overridden, the rest of that face's attributes are kept.

Depends on the use case. Please file a feature request, and please
describe your use cases there.
Thanks.
