YES!!! It would be a VERY good thing to have access to a 
set of color quickdraw patches. 20K extra?? 50K extra??
a small price to pay if the alternative is to not be
able to use some needed program.

However, the point Apple raises is a good one : all these patches
take up space, and there are times when they wont be needed
or wanted.  This problem already exists. The standard system
file has all the code necessary to patch all existing machines.

Thus a Mac+ is forced to carry around all the code to patch
old roms to look like the one it has, and also the code to
allow the Mac II to do things that the Mac+ can't  do anyway.

Sure, I can use ResEdit to remove the appropriate resources,
but this is error prone, unpleasent to non-hackers and impossible
to those without ResEdit.

A very similar problem is solved with the font/DA mover.
I can imagine a program very like it which could reduce the
system file to what is necessary on a particular subset of
existing machines (often a set of size 1). Now that we have this,
we can set a color-quickdraw-compatibility switch to tell it
that we want the above mentioned patches.
