Set Vibration API status to experimental.

Set Vibration API status to experimental. The current version of the specification is fully implemented. However, we still have a few questions under discussion so shipping to stable seems premature.

The approved intent to implement and ship is here:

There still is an on-going discussion about whether the current API is
sufficient, or whether we also want to add the ability to detect whether a
vibrator is available.

Should we make this feature experimentally available (i.e. under "Enable
Experimental Web Platform Features") until that discussion has been resolved,
rather than immediately shipping it?

You do have three LGTMs to ship on blink-dev.

That wasn't meant as a formal LG*TM, sorry.

Firefox and Android browser already support the spec as is right? I'd
say we should ship it as well and evolve the implementation together
if the spec changes. Otherwise we risk shipping different behaviors
across browsers.

Only Mozilla has shipped it.  The on-going discussions should move to a public
forum as well, allowing others to participate.

If the API will be changing then Mozilla will hopefully update their
implementation as well.  I don't think it's a good idea for us to ship an
unprefixed feature as long as we're vouching for syntax changes ourselves.

Should we set the status to experimental and send an intent-to-ship email to
blink-dev?

Ok to avoid a potentially premature stable release, we'll go experimental for
now.

I was going to send an update to the intent email after this landed. Would that
also make sense for this experimental status?

Thanks.

Ah, I'd forgotten about that.  Thanks for the link.

What I'd recommend doing is starting a new thread on blink-dev to let folks know
we're turning this on.  I'd probably include a link to the previous thread.  If
we don't get any complaints, then we can set the status to stable.
