I've never seen a boat with a roller furler that didn't have a turnbuckle on the forestay. You have to lock it, with nuts and/or with cotter pins, to prevent rotation. How else can you adjust mast rake, unless using vernier adjusters.
Of course, my not having seen one without doesn't mean they aren't made that way. I can't prove a negative, of course, nor will I try. I just haven't seen it that way.
A nice observation - I checked yesterday (in case I somehow missed something) my 1997 26X does NOT have a turnbuckle on my RF Genoa. I was kinda hoping that it somehow did. Now I'm wondering how to add one - it HAS to affect the forestay tension.

Nice post. I'm wondering if I could use a cargo ratchet around the shroud/mast and the mast - tighten it up - adjust the vernier/plate and then release?

With all the rigging in place, grip the upper shroud about 4 feet
above the deck and pull inboard toward the center of the boat.
The lower wire will go slack and allow another hole to be taken
up in the adjuster channel. To adjust the upper wires, pull inboard
on the lower wire. This method takes 2 people, and can get the
rigging tighter than is desirable. You can also loosen the forward
turnbuckle, make the necessary adjustment in the side wires, and
then retighten the turnbuckle. The final tightening of the forward
wire provides the final tightening of the entire rig.

Yeah, there's a turnbuckle there, but it's hidden from view by the furler. Removing a pin and moving the (CDI) furler body upward along the forestay exposes enough of it for adjustment of the turnbuckle (after the cotters are removed).
