If you cannot use a feature you'll get an error when you try to use it.
There simply are not enough capability bits around to waste on features
that are always true. If I reorg this stuff (and I intend to to split
crypto out into a separate features word because we are out of bits)
then I can look into expanding the status.
To be honest you're the first person that's even noticed you can list
capabilities in the 3+ years that's been in place (or at least made
public mention). Hardly seems like something that's constantly confused
people.
