I opened https://github.com/whatwg/html/issues/209 for the more general issue but am happy to have the discussion here since that hasn't gotten much replies. Do check out the examples listed there though. E.g. Blink is in similar situations with <dialog> and HTML imports. The web seems to end up with a lot of APIs like this, where the spec ends up just being documentation for a single-vendor implementation. I don't really know what to do in these cases. If our goal in writing these specs is to produce an interoperable web platform, then such features seem like they shouldn't be part of the platform. > as a point of practice, would seem to deter implementors from being first-to- > implement of something, or they might get caught like this.

Getting stuck with the only implementation of something is not good no matter what; having such features specced doesn't really make things better if you get caught in that situation. Going forward we can be more vigilant about this, and not add things without at least interest from two vendors, and preferably commitment to implement. The harder case is not about new features and who ships first, but about old features which only ever have one interested implementer, with no sign of that changing.
