For people who don't think they have an immediate use for either meshtastic or meshcore, it's fine to disregard it and just dig in further into the capabilities of the LoRA radios used. They can be used fairly effectively for some very long reach serial bridge connections for telemetry and command/control of DIY IOT things and similar.

LoRA is also used extensively for hobby size UAV handheld controller/ground control station to air unit controls, and in its narrower channel sizes can be very long range. The well known TBS crossfire serial bridge radio system which predates LoRA by a number of years uses a chipset that is sort of an ancestor of current-gen LoRA stuff.
