The greyscale ICC profiles I described are output profiles - more
specifically, printer profiles.  You are talking about workspace.  Dot gain
20 or whatever doesn't matter IF AND ONLY IF you colour manage the output
stage.  If you don't use colour management at the output stage you will end
up in the thread "Best RIP for 2200" to one degree or another.  My
recommendation is to stay in a generally used greyscale workspace like Gray
Gamma 2.2 (a direct subset of Adobe RGB) and colour manage the output stage
with one of the two printer profiles.  [I work in QTR Gray which is Lab
without the a and b channels but only because I find L* more intuitive for
B&W - I still can't think in Lab for colour!]


So use of the printer files (QTR-Gray Matte paper or QTR-Gray Photo paper)
is not mandatory - one can do whatever one wants - but if you want to use
the tool properly then you should.  Think of these two profiles as profiles
for generic printers for generic matte/photo paper.


If you send an RGB file OS-X takes it to greyscale on the fly.  Generally
not recommended.
