IScriptable Date Format [was: Deprecate ns IScriptable Date Format]
From bug 1301655 comment 0: > We shouldn't need to have an XPCOM API like nsIScriptableDateFormat for browser > UI JS to format dates and times with. Now that the ECMAScript Intl API is > available, UI JS code should use the ECMAScript Intl API instead of > nsIScriptableDateFormat so that the nsIScriptableDateFormat legacy API could > be removed. That bug is eliminating the existing users of the API in mozilla-central. As there will doubtless be other users as well (comm-central, add-ons, ...), we should explicitly deprecate the interface and point people (through documentation, maybe a console warning?) towards the modern alternative.
:jorgev, can we check for code that uses nsIScriptableDateFormat in add-ons, and prompt the authors to migrate to Intl.DateTimeFormat instead?
I see a number of add-ons using it. The ideal process in this case is to first deprecate the API and show a console warning when it's used. A release or two later, it can be dropped entirely. We can message the developers for both events.
This gives us a build-time warning when nsIScriptableDateFormat is compiled (at least on OS X; I'm not sure if all our compilers do that), and a simple runtime message in the browser console when it's used. I didn't make the message localizable, as that seemed like overkill here; I don't think we need to burden localizers with this.

Hmm, looks like we never landed the patch (attachment 8805914 [details] [diff] [review]) that was going to add a deprecation warning. :-( I guess it's a bit late for that now. Still, maybe we should land it here, and then have a followup in a few weeks to actually remove the code. WDYT?
I think we should not give an illusion that we still keep stability of the internal API even after 57.
We removed nsIScriptableDateFormat from C-C, so you can remove it any time ;-)
