we definitely should. One of the good things about 2e was that we 
finally removed the system dependent stuff or rather encapsulated it by 
providing  wrappers for color and graphic operations. So the same should 
be done here.

You still need the conditionals of course to make the wrappers work but 
ordinary code should use the wrappers eventually.

In the end that may be something we want to do too, but one important 
aspect with wrappers is that the right level is being provided (and as 
of now we may not have that inside. So if people with more experience in 
that area come up with some suggestions on what wrappers make sense that 
would be a good start.
