design size in DVI

On the net, I have obtained a DVI file (*not* TFM, VF, MF,...)
calling the following version
of cmr10:

-- checksum[4]: 11374260171 octal %%(standard!)
-- at_size[4]: 13.95...  %% anything goes
-- design_size[4]:  14    %% normally 10

My questions:  

(1) How could a design size 14 occur in practice?

(2) Does/should anybody or anything currently pay attention to
the design size entry?

If the answer to (2) is "nobody and nothing" then that is the place where
Berthold and others can stuff their extra font information rather 
then in the check sum, which is fraught with other conventions.
