You've lost me.  This is plain text documentation for a command which you
want to implement now but populate later.  Something like:

(gdb)
-list-features
^done,features=[]

AFAICS it won't currently return 'frozen-varobjs.  Since everyone seems
agreeable to the general idea why not just submit when the patch (source and
documentation) are complete?
