Thanks, @ericpre. I've launched the GH workflows for testing. (Manual intervention is only needed on your first PR ;) )

@jakirkham, @joshmoore, does it look good to you now? :)

[joshmoore]

Now green after upgrading the main branch to match 2.11.

[ericpre]

@joshmoore, @jakirkham, would it be possible to get this PR reviewed again please? Thanks!

[joshmoore]

I've relaunched the build. I don't know of any other existing solution and as this is a pure addition, 👍 from my side. @jakirkham ?

[ericpre]

Ping @jakirkham.

[jakirkham]

Sorry for the very slow reply. This seems reasonable. Let's get it in.

[joshmoore]

Thanks, @jakirkham! @ericpre: sorry for the wait. Do you want to push a blurb to https://github.com/zarr-developers/zarr-python/blob/master/docs/release.rst, then we'll get this merged? The only heads up is that 2.11 releases are currently slightly in limbo while we work on #1007 but that shouldn't take too long.
