PS2:

is this essentially bypassing the SMS queue? Each incoming SMS gets sent immediately? […]

I would not use the term "bypass".

If the immediate attempt to send were to fail then the fallback would be to the normal sms queue mechanism.

Yes, it's a strange beast. It's been a few months since I thought about all this, but IIRC, these patches were a result of attempts to refactor the SMS queue to do things, 1) stop it from consuming ENORMOUS amounts of CPU and blocking osmo-msc and 2) Make delivery of both newly submitted and existing queued SMS reliable according to the destination ME availability.

But, there is a pending removal of SMS queue from osmo-msc which makes these patches unnecessary.
