Not according to the official description of introspection annotations:
https://live.gnome.org/GObjectIntrospection/Annotations

However, if the gtk-doc parser doesn't trip over such annotations, it 
seems a good idea to include them for documentation purposes.  In future 
they may even be supported.  Others have clearly wanted to support this:

https://bugzilla.gnome.org/show_bug.cgi?id=672612
Generally the discussion on allow-none has extended to out/inout 
parameters and return values too:
