I'm not sure if you're suggesting that Apple intentionally held up
the standards process to get an advantage over other implementors, or
that simply it would theoretically be possible (and perhaps advantageous)
to do so (and in your non-hypothetical world, it happened whether intentional
or not).

Just in case it was the first one, I take no offence, but I'd like
to say that it certainly wasn't the case.

In particular, the standards process was delayed because I (and others
at Apple) didn't have enough time to devote to working on specs. Despite
having billions in the bank, we don't have the luxury of full-time W3C
editors like Hixie and Tab. If we wanted to hold up the standards
process we probably wouldn't have even proposed the work to W3C (after all,
these features shipped on iPhone first which had 0% market share at
the time). So we have a few choices:

- don't implement or propose the feature
- implement the feature but don't bother with standardization
- propose the feature before implementing (I would not expect much progress without an implementation)
- implement the feature and propose it at the same time (which is what we did)

Mozilla tends to take the fourth option (e.g. requestAnimationFrame, your earlier take on Web audio). Microsoft are doing something similar with their paged media work. I don't think there is any malice.

It's really regrettable that things stalled. I'm sorry. I can assure you
that the blame is not on the UA vendor in this case.
