Not really.  Mozilla used to inherit the old definition of computed
value, but it was a lot of extra work, and getting rid of that extra
work was the whole point of the change that introduced used values.

The point of that change was that inheritance would never depend on
layout-dependent computations, which it would if margin:auto has to
be inherited as a number.  It would be extremely silly to remove
that dependency for all cases but one.
