from what you describe it sounds like generic usage was not one part of
the design

and even then, most of that has to take place in the backend in order to
get proper integration (efficiency and such), so if for instance mp had
a model for arbitrary collections, like:
(r,g,b) == (c,m,y,k) => (a,b,c,d,...)
actually, colors in mp are just triplets

well, mp misses a few things but should not be compared to tex
(different model for globals, grouping, functions)

such code should not be inline, but in a config file or variable, seeing
this i'd say: for the moment forget about patching since it's hard to
keep up with such changes
btw, it should be:
if texengine == latex then texpreamble ...
else you need an abort for each macro package
