Interesting, thanks for pushing back and making me reconsider this!

i read the cargo specification for version requirements:

  https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#version-requirement-syntax

and it appears to be ambiguous about what an explicit comparator means
if the patch level is unspecified.

If you have evidence that this works, that's good enough for me.

Looking in git, i see that what you changed was just the explicit
build-deps (and test deps), without modifying the Cargo.toml patch.  And
i see that it builds and tests safely now ☺

Thanks for pointing me in the right direction!

Happy new year, Jonas!
