I only ever flash via CLI or via "drag & drop" method. The web flasher is great for first-timers but there are 100%-offline methods for all the devices.
The android client .apk can be downloaded directly from github at https://github.com/meshtastic/Meshtastic-Android/releases
I do agree though, I feel there should be more effort to support "long term lack of internet" use case.
For this use case - internet resiliency - I suspect the availability of un-flashed LoRa boards will be approximately zero in situations where it's needed. I agree that building an offline capable tool chain would be a good idea (perhaps all you'd need would be RasPi sd cards already flashed with everything needed to flash and configure common LoRa boards, and an archive of android apks?) But if I were allocating internet resiliency club resources, that'd be fairly low down my list.
