By offered you mean it decides to re-connect and in the middle of it there is a disconnect? Why do we need 2, and is it different with just one A disappearing?
Fallback AP may appear, but there is a 60s timeout if there are no clients connected (see wifi and wifi.stations commands output)

[adoeller]

No, I mean that ad-hoc and infrastructure will be permanently available. Even after 15 minutes.

Sounds like a bug in timers, then. Just not yet seeing the trigger...
edit ...but, re-scheduling from fallback::check() seems like the most obvious suspect here...
