Blocking `about:telemetry` should be set separately out of `DisableTelemetry`? about policy-templates

[mkaply]

That's an interesting idea. The big question is how do I change the old policy without breaking folks that want to block the page.

Or I could do something like "if the new BlockAboutTelemetry is set to false, don't block telemetry in DisableTelemetry.

would that be too weird?

Maybe use a new key and mark the old one as deprecated. (still internally compatible)

The new naming also more accurately reflects the parts that are disabled, rather than being guesswork.

{
	"Telemetry": {
		"DisableDataUpload": false,
		"DisableDataArchive": false,
		"BlockTheAboutPage": false,
	}
}

For sensitive prefs such as the Telemetry, it is best not to design too many keys at the top level, which will only increase people's confusion.
