Usecase: Use something below 1Ghz to transfer data to have better range then 2.4Ghz WiFi and have no need for a mobile carrier. At least in my country its not legal to run an own 700/800Mhz LTE network.
USB - i wont even consider registering to this forum if usb would solve this. Then i would use just any random phone supported by postmarketOS. If the LTE modems from all regular people would have to be connected by USB, i think most people would have complains about such unhandy solution. How should i even put a usb-lora-adapter together with a phone into my jeans-pocket like most people carry their phones and then wait for this unhandy thing to vibrate to notify me about anything new?
Battery life - If i would have a phone that would fulfill this usecase for some hours and not a full day, then i would have a phone that would fulfill this usecase for some hours and not a full day. At the moment i have 0 seconds long lasting solution for this usecase.
As I understand tllim's message, the last "restock" was really just some leftover items having been found in some hidden shelf. There was no new production run. So it is unfortunately unlikely that there will be any further restock. (See also the discussion about the keyboard case.)

If you cant find one available it is pretty easy to make one using a pogo-pin ribbon and a LoRa module, I cant remember the product mumber it might be on the LoRa caseback product page I think the module was under $5 a few years ago. Currently it is only serial communications where you need to write your own software.
if you go the DIY route it is super easy to cut a slit into a standard caseback and then kapton tapi it down then cover with ABS/acetone cement I just use 3D print ABS scraps and store in a polyethelyne bottle. It is literally among the easiest pogo-pin DIY hacks if you dont mind a melted ABS looking caseback.
(edit)It looks like there is an attiny inline to control the I2C so maybe not as easy
