Thanks Tobie, that does sound related, but not quite the same use case.
That proposal seems to want to make the creation of memory/network/runtime
performance profiles scriptable if the user allows it. Presumably you
wouldn't do that routinely, which raises the question of when you would do
it. Once the app has crashed it's probably too late. I foresee this
mainly being used by groups of users 'friendly' to the application author,
such as employees of their firm, qa testers, etc. Their privacy issue
isn't so bad, either, as there would be nothing in those profiles which the
app author didn't in principal have access to before. I'm also not sure my
use case falls inside the performance working group's charter. In any
case, I'll reach out to them and see if they're interested, thanks.
Ian, I'd be interested in what you had in mind when you said 'a lot of
Presumably you don't feel a permission dialog raised at the time of the
API call enough, were you thinking of a browser configuration setting, off
by default? That's very limiting, you'd be down to 'friendly users' again.
Your other objections I think could mostly be dealt with. I've specified
that user agents supporting the screenshot have to provide a blackout tool.
Also, in some ways the more annoying this dialog is the better, as it's
supposed to be something devs only use if they really need to. You could
focus the 'no' button by default, or make it unresponsive until a timeout,
stuff like that.
I'll raise this with some of the browser vendors directly as Ian suggested.
