No, of course not, and GNAT will certainly not include the
tasking unless it is used.

Of course, there are 500 units in the GNAT library, you get only
the ones you want. There are however, some base units, e.g.
basic exception handling, that are in all non-GNORT generated
programs, because they are virtually always needed.

I can't imagine any Ada vendor saying that, it is nonsense.
Also, let's be very careful not to obfuscate here, "bigger"
and "slower" have nothing to do with one another. We have been
exclusively talking about *size* of trivial programs here,
absolutely no claim has substantiated about identical programs
showing difference in speed performance!

Well slower would be a concern, the fact that a hello world
program uses 0.2 cents of disk space instead of 0.1 cents
is a dubious concern.
