That would make me feel more comfortable, yes.

Daniel proposed "firmware-max-size" (I've now taken the liberty to
replace "_" with "-"; I believe that's the current rule for property names).

If we called it "x-firmware-max-size" and kept the default value
unchanged, I'd feel way safer. (Because then any feature request for
upstream OVMF that were based on changing "x-firmware-max-size" could be
refuted immediately with: "that property name starts with x-, sorry".)
