OK, I can check --list=build-info and try to parse john's the version
string if format interface version is 9 and assume that it is supported
if format interface version >= 10.
Or people who use a jumbo version <= 1.7.9-jumbo-8 just have to live
with the fact that bash completion (currently) lacks support for some of
the features.
When do we release 1.7.9-jumbo-8?
May be I find some time to implement this during the weekend.

No, I don't like this.
If we need to implement anything, we can come up with a variable
(similar to format flags) not intended to be human readable (unless some
user complains) and gets printed in the --list=build-info screen.
As long as there is just one feature (supports format classes and
generic format names) mapped to that variable, it might look a bit silly:
Supported features: 00000001
But that will certainly change over time.
