this completely ignores the use case where the

Yeah. However, merging patches (especially when
changing heuristics, especially in page reclaim) is
not about just thinking up a use-case that it works
well for and telling people that they're putting their
heads in the sand if they say anything against it.
Read this thread and you'll find other examples of
patches that have been around for as long or longer
and also have some good use-cases and also have not
been merged.

What do you think Andrew?
Swap prefetch is not the panacea, it's not going to solve all the
problems but it seems to improve the "desktop experience" and it has
been discussed and reviewed a lot (it's has even been discussed more
than it should have be).

Are you going to push upstream the patch?
