The only way Line 6 sees feature requests is if they're submitted here: http://line6.com/company/contact/productfeedback/

I do kind of agree with you that they probably should just make the new model available to all JTV owners. I don't think there would be anything preventing them from doing it, but I don't know for sure. I'd also be interested in hearing how the new model compares to the existing Les Paul model.

A couple of "educated speculations" about this.

- I think it's very likely that Line 6 will eventually make these (and, probably more) pickup models available to the other JTV models, sooner or later. If they could sell virtual pickups, that would give them some extra cash flow in exchange for R&D that they've mostly already finished in modeling the original Variax pickup models.

- In order for them to integrate more pickups naturally into the Variax, they need to alter Variax Workbench to accommodate them. That's more complicated than it seems. Variax Workbench was made for the original Variax, and it's likely (I'm inferring, since it is taking so long) that Workbench was not originally made with easy extensibilty in mind, so they are having to rewrite / make major revisions to parts of it.

I'd also say that, since the high-gain pickups are hard-coded into the JTV-89's "Custom 2" bank, and you can't access them in workbench at all, that lends some more supporting evidence to the second theory.

Of course it's human nature to feel jealous, or think of what you've got as being "less," when someone else gets more. But try to remember your goal: to make music! You've still got a good guitar that you can make music with, and you never know what might be in store for a future update.
