Intrepid is in the same state, although our release manager calls it
feature freeze. Changing the boot definitely falls under this category.

I've been working on some of these slower netbook devices lately, and I
have to say that having them blurt something to the console once in
awhile during boot lets me know they are still work. Granted, I could
just as easily edit menu.lst myself ...
This whole issue ought to become moot sometime after Intrepid. The new
holy grail is the 5 second boot. Anything that clutters the boot process
is likely to get ripped out.
