Sure, I thought about just one tag for pre-reform orthography yes,
it's reasonable to assume that the default would be the modern one

Ok yes, makes sense. I'll try to find a reference point; my
understanding is that it will be quite arbitrary as there seems to be
a continuum of reforms; and it seems not very productive to identify
each one with a different tag.

Oh, so it's better if it contain the name of the language? something
like -kmpre20c ?
