Sure, the ones using it for tracking that care *that much* will use
other solutions anyway.  But people who just want some persistent
storage as part of their app, because it's useful to their users, will
use the browser-native solution if it works.  If LocalStorage is
explicitly supposed to be as ephemeral of cookies, though, that will
push people towards stuff like Flash LocalStorage instead.

I think a lot of people weren't that aware of Flash LocalStorage, but
more will be now that we're talking about it.
