THE BEHAVIOR MAY CHANGE. I think the wording needs to be a bit more detailed; you copied the wording from git-switch.txt, but usage of git-switch is not expected to modify the behavior of other commands. sparse-checkout, by contrast, is designed to affect other commands: at the very least checkout & switch, and likely will affect grep, diff, log, and a host of others. Perhaps something like: THIS COMMAND IS EXPERIMENTAL. ITS BEHAVIOR, AND THE BEHAVIOR OF OTHER COMMANDS IN THE PRESENCE OF SPARSE-CHECKOUTS, WILL LIKELY CHANGE IN THE FUTURE.

I was taking your comment to mean "this builtin is experimental" but what you really mean is "the sparse-checkout feature is (still) experimental". -Stolee
