Also could we abstract this away for the user? So that developers of new backends have to understand `obstore` but people calling `open_virtual_dataset('known_filetype.nc')` don't?

Hi @darothen - although we're planning to release v2.0 this week, that isn't slated to include GRIB support. However @sharkinsspatial has been working on a GRIB parser very recently, so...

Very interesting @frazane ! Is EarthKit able to export the byte ranges? Do you have any code to share?

Whilst this passes the CI tests, it doesn't work at scale for this weird reason that I don't yet understand - see https://github.com/lithops-cloud/lithops/issues/1429.

> this lithops failure Umm that's weird. The CI is using lithops `3.6.0` - what are you using on your machine? (Though it worked on mine too ofc and `3.6.0`...

Thanks, @sharkinsspatial - that's annoying about Lithops but it definitely makes sense to push that problem to another PR. Would be good to open an issue so we don't forget...
