> Here you make the assumption that the board you are running provide non volatile storage which might not be the case all the time.

True. But in practice, boards in a real deployment should include non volatile retention mechanisms. Considering the consumption in STANDBY can be e.g 60% of STOP mode, IMO we should aim to have all LPM regardless of the activation mechanisms. If a board doesn't include a non-volatile storage, then it could still run with STOP mode. But I wouldn't block OTAA users if they want to run in STANDBY mode.

Yes, indeed.

The MAC can in theory run with only one timer, but we would need to patch a little bit the OnMacStateChekTimer function. I think that could help us in this direction.
