what is the spec of arc? do you need that one or can you map it; i store 
paths in 6 point sets; how is arc used?
I may consider providing a hook for such extensions.

One thing to keep in mind is that supp-pdf catches some special mp things 
like pen-stroked paths

do you have an example?

i have no problems with supporting setlinewidth directly

not per se, if i know the syntax and what to expect ... of course the file 
should be made known to tex somehow

no, since mp used floating point too; but there are some constraints to the 
maximum size and small sizes can get rounding errors although this only 
counts in penstrokes.

So, how does such a file look like?
