It’s unfortunate that we need a rule that is not the same as what’s in HTML5. We should raise this issue with the HTML5 folks.

In the process of drafting an email to whatwg I convinced myself that this is the wrong approach to take. By permitting object elements with classids, we can end up loading content meant for an ActiveX component in a Netscape plug-in in certain circumstances (e.g. the url happens to have a file extension that a Netscape plug-in claims to support). Preventing a plug-in from loading content not meant for it is the rationale behind falling back for non-empty classids (even falling back to nothing). I don't think we should allow this to happen in general just because we happen to know that doing so is safe for this one case.

I think a better approach for this case is to restore QuickTime's classid mapping (perhaps even wrapped with a site-specific hacks runtime guard). It seems safer to specifically permit loading QuickTime in this manner (under the assumption that content loadable in the QuickTime ActiveX component is also loadable in the NPAPI plug-in).

Is this a problem with Mac OS X Wiki Server, or with Podcast Producer specifically?

It's a problem with any QuickTime movie hosted by Wiki Server.

I think we can remove this quirk now since OS X Sever shipped with Mountain Lion and later has been emitting video element as fallback.
