I'm pretty sure that Binyamin meant exactly what he wrote.
Firstly, he suggested that, if there were such things,
"standard" exits might emulate default, i.e. non-exit,
behavior.
Secondly, he went on to describe what exits are normally
used for, i.e. anything but default behavior.

You actually seem to be talking about two different E15s and E35s here,
although I don't think you meant to.
In your first paragraph, you talk about the E15 reading SORTIN, and in the
second paragraph you talk about the E15 generating all of the records
(equivalent to not having a SORTIN). Those are two different types of E15s
with different logic. Likewise, having an E35 write to SORTOUT, and having
an E35 consuming the records (no SORTOUT) are two different types of E35s
with different logic.
I wouldn't call either of those E15s or E35s (or anything else) a
"standard". Given that how you would generate and dispose of such records
in the no SORTIN/SORTOUT case, and how you would manipulate the records in
the SORTIN/SORTOUT case, would be quite different in different situations,
I don't see how/why you would apply the "standard" label in any of those
cases.
But maybe it's all just semantics.
