It's right at the limit, just shifts far enough to get into the big ring and not rub, limit screw (or whatever it is) is all the way in.

When I bought the GRX crank I included the front mech + clamp.
Turned out the R8000 mech worked just fine.
The GRX + clamp was an extra €20 over the R8000.

Surely there is sound technical reason Shimano states the R7000 & 8000 are incompatible.
Maybe we just got lucky with our bikes?
Kudos to Shimano mechs for being so forgiving.

I think the only difference is that there is a larger Q factor on the cranks and the derailleur is further out to give room for wider tyres. There's a bit of adjustment on a mech which I guess most of the time covers the change and they just want to cover their backs?
