So I think these are valid use-cases, and I just think that they should

 (a) be documented in the commit message as explanations of why people
would do this/

 (b) not be called "stacked", because that tends to have some other
connotations to fs people.

I don't know what a better term would be, but you yourself used "pass
through". Maybe that (perhaps together with a clarification that it's
a per-file thing) might work fine.

Btw, why is mmap not passed through? That sounds fairly simple and
straightforward, I'm not seeing why it would be missing.
