I have pulled wall to wall since Heavensward...back when it wasn't really a thing...I just found out that I could do it competently. It became a thing in Stormblood and was pretty much standard in Shadowbringers.

I never really considered it was toxic to pull wall to wall. Only thing you have to watch is if your healer can keep up. All depends really.

I think the one thing that I considered toxic was a healer using rescue just to pull me through a dungeon...just to speed things up? I would just say...please don't do that. Then I would just get a dumb comment like..."Hurry Please"....which would just make me want to sandbag more just out of spite. Deliberately not use a mitigation...not AOE effectively, etc; Just the bare minimum to hold agro and not sprint between trash.

I normally pull wall to wall, but when I get that rescue for no reason...that's where I draw the line.
