Could you provide your rationale for wanting expressions like
this to fail? Maybe there is something we've overlooked?

I'm inclined to agree. As long as the dimensions are correct
and a.) the result type is the dimension of the unit, or b.) the
programmer specifies the desired units, I don't see a problem with
implicit conversions between quantities (measures, whatever) of
compatible dimensions and units.
