> It's not like they're "removing" it, they rewrote half the browser and not all of the APIs are hooked back up yet

For most users this is a distinction without a difference.

What part of "it ain't finished yet" would most users not understand?

It's a Preview release for a reason. Mozilla aren't exactly pulling a KDE 4 here.

It was a preview release, but they've already started rolling it out to the regular Nightly channel and according to this very blog post we're discussing it's supposed to have a "public release later this spring".

Given that any changes have to work their way through the Beta channel, too, there's not much time left for landing changes in Nightly that will still make it into the first Release version... so the first official Release version that will be pushed out to everybody will indeed be in an unfinished state.

The distinction to me is they removed it but didn't also deprecate it.

It's not like they're removing it. They'll just push an update and your extensions will be gone.

A lot of corporate communication wizards might be required to dress this up as something else than direct removal.
