Brilliant idea! I too would use an inverse match logic. Shorter rules,
easier to apply, probably faster.

I guess that I should interpret that as no, there isn't such an incantation
but since I brought it up then it's my job to write the code so I will when
I get a chance.
You don't need to write anything. From mhl(1):
The component "Extras" will output all of the components of the message
which were not matched by explicit components, or included in the
ignore list. If this component is not specified, an ignore list is not
needed since all non-specified components will be ignored.
So just remove "extras".
