I still kinda like the idea that gets tossed around sometimes that the Joker wouldn't care that much about who Batman really is, and that it's a Joker vs Batman thing because Joker vs Bruce Wayne isn't as fun.
Other villains would LOVE to see who Batman really is, though.

Yeah, but there's probably not too many hyper-wealthy, black-haired /fit/ men in Gotham other than Bruce Wayne that'd fit the bill as Batman, and Bruce Wayne is so famous that it'd take like 0.1 seconds for him to pop into Joker's mind, connect the dots and confirm it to be him.
