Please. You have to stop questioning features *after* they are implemented. This bug is almost 14 years (!) old, and Mozilla always had addons, that's plenty of time to raise objections like that, not when there's a patch ready to land.

I an using the "Virtual Identity" addon since many years, but that very fact that I need certain addons (I can't use Thunderbird without them), and that they are not always up-to-date, prevents me from using Thunderbird trunk. I'd like to use a stock Thunderbird trunk build, at least for my most important needs, without depending on addons for everyday work. I currently have to use an age-old Thunderbird (which is insecure), because of the addons. Addons are good for integration with your telephony provider, but not for basic emailing needs.
