Yes, it isn't different but my point was that introducing stylistic sets
as a face attribute is more desirable than just having a text property.
Using a face attribute means we do not need to rewrite/add code to use
stylistic sets in certain cases, it is a matter of customisation.  IOW,
I am not saying that we should only have a face attribute.

See above.  Hopefully, I made my point clear.
