Ummm... No. See my previous comment - at least in Rails, the queries aren't part of the data object themselves, but are instead mixins or default handlers (don't recall which offhand), so it's really just syntactic sugar that makes it appear as though they are methods on the data class.
Even if they did the same thing you're suggesting, by that logic, we should all use PHP because WordPress does, and it's probably more popular than those two combined.
Take a look at something like Spring or Entity Framework to see other takes on ORM patterns.
And again, you're trying to argue against ORMs, while citing that your suggested alternative is supported by the way ORMs do it.
