Actually some apps did have fullscreen support in SL, so it really depends on if the app keeps legacy fullscreen support or not, in VLC in preferences you can switch to the old style at least and watch a movie in fullscreen while continuing to work on your other screen.
The old style was a hack really and as you've pointed out, is still available to developers. If developers are moving away from it, it's because they see the advantages of the new system over the old one.
Work while you watch a movie ? Listening to music, ok, watching a movie ? And work ? Can you even do that with any chance of success at either ?

It also fucks up professional settings btw, where a projectionist might want to display a movie on the secondary display (projector) while cueing up the next one up on the primary one, or some such similar situation.
Hum, projectionists use Quicktime Player now ? It's a "pro" tool ? Projectionists can use whatever still works for their workflow. Someone pointed out earlier that VLC retains both modes of full screen. There is no limitation to Lion that prevents it.
Here, I've definitely lost something. If you can't see that, I don't know what else I can tell you.
You haven't lost anything, since again, developers are free or not to move to the new system. Provide feedback to the developer of your app, explaining calmly and professionally, using full sentences why you think they need to retain the old way of doing full screen on top of Lion's way.

Don't bother. People like him can't be reasoned with. Apple brainwashing at it's finest.
Why is it that I have to either be Apple brainwashed or a Apple hater ? I can't be both, yet you call me Apple brainwashed and everytime a story about trials or App store guidelines or heck, just bad changes in OS X/iOS come up, people label me a hater.
So which is it ? Am I a hater or a blind fanatic ? I'm really getting confused with you people...
Oh wait, it's because none of you guys can recognize good ol' fashion Critical Thinking and Objectivity.
I'm neither an Apple fanatic or a hater. I use their stuff, like some of it, don't like other parts. That's called a balanced outlook. Don't have to be 100% on either side, there are shades of grey to the world. Time some of you started to realise this instead of always pigeonholing people into your own mindsets.
