This would be quite odd and not what I had in mind when I suggested this.
But I probably didn't express myself good enough.

I'd be fine with this, but as you mentioned, it needs a re-review of the bindings.
If it's just about the label being used upon GPIO request, I might switch to
devm_fwnode_gpiod_get_index to explicitly set a different label and keep
"shared" in the bindings and device tree property?
