Not sure why the build is failing for -Z minimal-versions.
As far as I can see all our pin* dependencies are fixed to a patch version.
@taiki-e any ideas?

Turns out pin-project-lite added the ability to specify a projection name in 0.2.6.
Doesn't seem to be strictly semver-compliant, but at least we have it working now.

Doesn't seem to be strictly semver-compliant

Note that if the major version is 0, cargo treats the minor version like the major version and the patch version like the minor version.
