The code you load in Emacs 23 that's written for lexical binding often
won't work, though. (I.e., if the code uses closures.) So it's not
backwards compatible, just as code that uses "new" macros like
`with-current-buffer' isn't.
Emacs Lisp develops, and newer versions aren't backwards-compatible.
That's just how it is. If you're maintaining code that's out of tree,
you have to avoid using the newest features. There's nothing special
about the new `interactive' signature in that respect. (And as Stefan K
shows, if you still want to use it in an in/out-of-tree package, he's
written a compat macro for that.)
