I was actually at Roland/BOSS when GT-10 came out (2008), but what do you feel made it a UI standard that wasn't already reflected in, say, POD X3 Live (2007) or even POD XT Live (2004)? I mean you could go all the way back to the GT-5 (1996) or at least mention the VG-8 (1995), which was the first floor-based processor with digital modeling in it. And of course there were all the pre-modeling floor-based multieffects from Korg (A5, 1991), DigiTech (RP-1, 1992), ART (ECC, 1995), and others. Not pushing back, just curious.

Regardless, anyone implying that Line 6's design team ripped off Headrush or Neural's UI for Stadium—instead of basing it on our own touchscreen-based Helix designs from ~2012—is straight inhaling jenkem.
Yep. You can also bypass the block and from the action panel, copy and paste it in place.
