That's pretty much what "cr" and "return" do already.

It's a holdover from HyperCard and SuperCard, where "return" has been in
use since the beginning. As you say, it's very natural for anyone coming
from another xtalk environment. The synonym "cr" is what others probably
want to use, it's the same thing.
I'm not convinced we need a new constant though, but of course I could
easily be missing something. I have always just used "cr" or "return"
(interchangeably) and line endings have always been converted correctly
no matter what platform I move my stack to. Never had any problems with
it. If hard binary data needs to be converted, as in the case we've been
discussing, then I just replace the appropriate ascii characters with
"cr" or "return" and it fixes things. This also works when writing text
files; the correct line endings get written depending on the platform. I
suppose if you were writing binary data, you'd need a switch statement
to write the correct line endings depending on platform, but those
constants already exist.
