Well, if you have the E-package, then you would also need the L-package.
Using the E-package alone, without also using the L-package, is not
possible.
Remember, the E-package, defined in appendix B.4 of TS 101 909-4, is an
extension to the L-package, that was defined out of a need to map V5 signals
and events to NCS. For instance, there is no way to let an MTA play dial
tone using only the E-package; you need the "dl" signal from the L-package
for this.

My idea of the "ETSI systems" and "non-ETSI systems" terminology, was that
an operator that uses the L- and E-package would fall under the "ETSI
systems" category, and an operator using the L-package alone would fall
under the "non-ETSI systems" category.

I believe that this is the source of the confusion; you maybe interpreted it
as if "ETSI systems" referred to E-package *only*?

In any case, it would indeed be beneficial to clarify on what "ETSI systems"
and "non-ETSI systems" mean in this context.

With this in mind, is my proposal not the same as yours, then?

Regards,

David
