You started this sub-thread with:
"If I understand correctly..."
I'm not sure that you do...
Our scheme is, in your terms, basically:
<major>.micro
where <major> is a decimal.
You cannot reason about the whole and fraction portions of the decimal
independently.
When <major> changes backward compatibility can be broken - with respect to
both API and implementation.
It therefore makes sense to

I'm not convinced there is enough risk here to compromise the present in
order to accommodate some unknown scenario that may never even come to
pass.
