Pitfalls to avoid?

I was wondering if there was a general list of known pitfalls to avoid with Animate, regarding future-proofing, dependencies, etc?

Prior to the release of the iPhone, I developed websites with Flash elements. Shortly after the iPhone, I suffered a head injury - and when I started to recover, everything I'd ever created was a broken mess.

But that's just not with Flash - my CMS's were destroyed by a new version of PHP being installed on the server, etc. Really, the head injury just couldn't have happened at a more opportune time

I realize it's not possible to future-proof anything, because who knows the future?

But, if the code that Animate publishes has a zillion dependencies, any or all of which could be "deprecated" at any point in time, leaving everything broken - I'd just really appreciate any heads up on those features it would be best to avoid?

What makes me most nervous - so far - is that multiple canvas elements should (apparently) be embedded using iframes. You'd think Adobe would have enough resources to provide a solution that isn't a "workaround" to their own code - but apparently not?

And I plead ignorance across the board. Maybe I'm an idiot and iframes are the most elegant solution? But, if so, then why was I forced to hunt for an answer to that problem on this forum? Wouldn't that be a very common issue, and shouldn't Adobe have an official solution, at least by now? Multiple instances of Flash were never an issue.

From my standpoint, animation is cute enough - but it's not so cute that I'm willing to force what might be hobbled code into my sites. No way I'm ever touching a CMS again, and - if I can - the farthest I'd ever go with PHP is the include statement I'd very much like to avoid technology that I don't understand.

For me, Animate would be a cool tool for quickly and easily producing animations that I can integrate into my designs. And I'm very much hoping to hear back that it's very solid and that the iframe nonsense is likely only because Adobe would like to help try to "inspire" me to use Dreamweaver to manage my sites?

But I'd greatly appreciate ANY feedback on pitfalls to avoid, and whether folks trust that Adobe has future-proofed whatever "code" is output by Animate as best they can.

Thanks!
