    I did actually run into this today. One of my pipelines is configured to
    clone a bare repository, then set up a sparse secondary worktree. This
    used to work, but all of a sudden, the git config --worktree
    core.sparseCheckout true call failed because I'm now using v2.28.0-rc0.

I guess a few people were independently hit and then approached the
same issue from different angles?  If so, can you two compare notes
to help us all come up with a single good solution, preferrably by
-rc1?

Thanks.
