I would like it more too, but in M3-W dtsi:

		pciec0: pcie@...00000 {
			reg = <0 0xfe000000 0 0x80000>;
			/* placeholder */
		};

So I kept using the same style everywhere here.

I can change it everywhere in this series to have placeholder at the
beginning of the node definition if you agree with that!

Thanks
