Absolutely agree regarding difference in approach – and I'm by no means suggesting that yours is in any way worse! In fact, I believe yours is much, much better given the more general use cases it supports. Ours is inherently stateful and requires careful coordination, which works for us because the system is pretty much self contained and it makes things easier, but I don't think it's a good generic solution to be honest.

My point was really that it's nice and validating to see the the whole idea of a unified way to "query all the things!" as it were isn't all that novel. :o)

By the way, if you can think of the name (or a URL even!) of that project you mention I'd be very interesting to take a look at that too. Much obliged!
