+1 for pipe-as in contrib.

But frankly I'd be glad seeing *any* of these macros in contrib.macros
(this one seems quite abandoned with 3 macros only, huh?) or wherever
in contrib. Let the contributors decide & go with it, that will push
it to use, for good.

I wrote a bunch of similar stuff but not so general; it arises from a
need to control order of passed forms while sticking to 'threading'
style, as this style helps in grasping how data is transformed (btw
it's a thought raised a couple of times, see eg. recent blog of Tim
Bray cited here).

It'd be very cool to see these threading augmentations standarized a bit.
