Isn't support a baseline issue? If it isn't well supported, it is unreasonable
to put it in the baseline, which means that you can't use techniques that
rely on it. So I don't understand what the loophole could be.

Roles in XHTML are not the only example that supports Lisa's case:
XForms has a range element with start, end and step attributes, so
min and max values can be programmatically determined.
