The reason, Graeme, has to be “commercial”, IMO.
Otherwise, people would have no reason to upgrade to an M1 device.

I was informed by X-rite it is due to a hardware limitation with the iSis REV E
(last of the gen. 1 devices). Perhaps the power or the spectral emission of the
UV LED isn't what is required to compute M1? They wouldn't tell me specifically.

That would make sense for the Isis2, but the original ISIS only had M0/M2,

that gave me pause is that i1profiler will only allow an M0 measurement in a
“double scan”
mode, which takes twice as long, whereas it will do M2 as a single scan.
The double scan is because it makes a separate UV pass before combining the
two passes. In M2 it simply turns the UV LED off.
There's no technical reason why the iSis 1 couldn't compute M1 - I'm not sure
why X-rite would choose not to do so, since it just involves a different
weighting of the UV and non-UV measurement passes.
Cheers,
