I haven't fully got my head around how you can be 'unitless'. Is the idea that once I've input the number of steps required to move one of my chosen unit (mm, micron, yard, cubit) the software simply treats that many steps as one 'unit'?

That's exactly my intended meaning. Whether my meaning is right or wrong... but I think it's right. I normally get a "ignore-me pester box" whenever I import g-code from Fusion that typically complains about the first G20/G21 as an unsupported command.

Aha, if you'll support a remote link... http://cncdrive.com/forum/viewtopic.php?f=4&t=769

Very helpful, thankyou. I'm sure it makes a great deal of sense really.

I've just had a look at the available postprocessors in CamBam and all of them include G20/21, though I've had a look on the CB forum and nobody has complained about it not working. Fortunately that forum is as good as this one (it has at least one star member in common) so if I decide to write a bespoke PP there will be plenty of help available.
