This works, but the error is too cryptic. It just says none of the
OPTIONS_SINGLE options was selected when really the selected one is gone.
Yes, it is exactly what I stated as my primary goal above (not offer the
option), but I realize now what I really wanted was to offer _no_
options, falling back to just USES=gssapi:mit,flags as before.

Much nicer, although it lets the user select the inapplicable option
first and refuses to work only after that. Too bad.
Thank you!
