Many years ago I started work on a timeline editor for SMIL, but it was 
just a hobby and I had no actual need for it so it never got very far. 
Seeing where Apple's support for it is now, maybe letting it go wasn't a 
bad thing.

It's too bad, though, because SMIL serves a role no other spec provides. 
  If Apple's serious about making good on their anti-Flash agenda 
they'll have to at least support SVG animation, which incorporates a 
fair bit of SMIL.  TTML also offers a lot of promise, and also 
incorporates some aspects of SMIL.

The most unfortunate thing about this is that searching for "SMIL" at 
the Apple dev site turns up zero results - not even a page noting its 
deprecation, or a redirect for the URL they apparently dumped.  Clumsy.
