For Gecko it depends.

For example, we plan to ship a PDF viewer plugin (based on pdf.js) that 
we may decide to allow in sandboxed iframes.  Will need to audit it a bit.

For third-party plug-ins, I suspect the "never" answer is a good 
assumption for now.

Actually, sandboxing iframes of your own site is one of the main sandbox 
use cases: it allows limited user upload of content without creating 
security holes, in theory.
