I do have a solid calibration mic and have done this a handful of times with different speakers, but like you've said, I'm very much technically inclined and wouldn't expect the average person to be able to do it. It's probably just a matter of time before pretty much every speaker can self-calibrate to some degree. Most mid-range bluetooth speakers already have a microphone and some basic DSP abilities, which is really all you need. HifiberryOS is new to me and looks pretty nifty - I'll have to check it out.
