More than that - I believe its the only way something like this (which is 
really needed) is going to get into boost at all.

I think that it would be best to start with a dimensional analysis library 
and not worry about units at all until latter.  I subsequent units library - 
there might be several would be built as "users" of the dimensional analysis 
library.

This way, there would be a lot less to try to agree upon.

layer 1 dimensional analysis core
layer 2 specific dimension systems - usages of the above library - probably 
more than one
layer 3 units core - extension of dimensional analysis library
layer 4 specifice units systems.

Now I know from experience that lots of people will find say - "if it 
doesn't include xyz... its just useless".  Well, those people are wrong.  If 
sufficient number of people find the lower levels useful, it can accepted 
eventhough not eveyone wants to use it.

Also it would make the library(ies) much easier to understand and use.
