- the "auto" is like if there's no annotation.
- the "yes" seems useless because there is no case where the 
scanner should fail to detect members that are managed by the GC. 
It's for this case that things are a bit vague.

Otherwise only the "no" remains.

So far I'll go for this: https://dpaste.dzfl.pl/e3023ba6a7e2
with another annotation type name, for example 'AddGcRange' or 
'GcScan'.
