At least once UA is already using !important UA rules to mean "highest
level possible" (i.e., even overriding user !important). This is useful
for preventing certain things from being overriden, e.g. styles on
<input type="file"> or the styles of internal pseudo-elements.

why should a user not be able to override the default rendering of <b> but
should be allowed to override the default rendering of <strong>? That
makes no sense to me.

No, unless I'm not part of the group claiming consensus. :-)

I don't understand why I would want to override the default UA rendering
of <strong>, but not the default UA rendering of <font color="obnoxious">.
In fact, I imagine I would want to override <font> a lot _more_ than I
would want to override <strong>.
