I agree, It's the best one we've got.
Even better, how about just ONE, world-wide seniority list? Impossible to create I'm sure, but if it existed, then you could easily bid for whichever vacant post was next. It could be an FO on a BA380, or a skipper on an RJ in your favourite town, or a LH737 skipper in Berlin.
I know, I'm dreaming.
