Yes, you're absolutely right … fiddling with the fonts is going to  
spoil my day!

Now what about this: I've just realized that mptopdf actually runs a  
ConTeXt background process that appears to have its default font size  
set to 12pt. Incidently, my TeX labels come out at exactly 12pt …  
since I'm almost always going to use mptopdf as a compiler anyway  
could I perhaps make it run the ConTeXt process at 10pt font size?

Thus I'd probably get the opticals right and someone else would do the  
fiddling for me ;-)
