Disclaimer: I did not look closely at what Automake actually does.

I suspect the reason is that EXTRA_SCRIPTS doesn't really make a lot
of sense, so nobody has ever tried it before.  That would mean "the
following scripts are not distributed, not installed, not built by
default, and outside of the scope of any built-in Automake rules".
In other words, it is saying that Automake doesn't have to do anything,
so the expected behaviour is the same as if you did not write anything
at all.

By that token, dist_EXTRA_SCRIPTS means "the only thing you need to do
with these files is include them in the tarball".  There is already a
variable for that: EXTRA_DIST.

I think Automake probably just ignores both versions (i.e., it treats
them like ordinary make variables).

There is probably an improvement to be made (either to Automake or to
the manual), since the documentation does say that there is an EXTRA
version "for each primary" (which would include SCRIPTS) in §3.3:
