1.64 is basically unusable now, as it doesn't support sparse index for cargo. That means building anything takes ten minutes.

The actual MSRV remains as 1.64.

I don't love advertising an actual MSRV lower than the tested MSRV, but I guess for these particular super boring crates it is probably acceptable?

I guess there are some other options to this:

  • keep 1.64, and add some sort of GHA caching for the crates index
  • actually just accept a MSRV bump (if it is annoying for us, it sure as hell will be annoying for anyone else)

I would be slightly more inclined to just bump the MSRV. 1.70 is 34 months old at this point.
