This was also something I had in mind, along the lines of what Tomas
wrote below:

So yes, I also agree that this could be an extension opportunity, but I
wouldn't push it further until we have concrete use cases.  It is
usually futile to try to generalize from zero examples.  (Well, I do
have one example, but still.)

For the time being using inline checks within the specification suffices
for me.
