Because you’d have to stash your modifications to be able to switch branch.
OP said nothing about stashing, only committing WIP commits to feature branches. I don’t think none of your remarks apply, because if you really need stuff from the WIP commits you can also cherry-pick them or checkout specific files.
If you find it more comfortable to keep swapping checkouts in the same dir that’s cool. I’m just explaining that some of use find it easier to keep several different checkouts around, and sparse checkouts are helpful when you do that.

Fair enough.
