I think the chat integration is the last remaining puzzle piece. If thunderbird had builtin chat and builtin gpg support I'd be content. I have never understood why smime was baked in but gpg was not. Enigmail should not need to exist and unlike any other ff/tb plugins it used to be a pain with amd64...
Enigmail works great here. I don't really see a need to bring it mainline, perhaps other than encouraging adoption. I use 64-bit and have used Enigmail for 3+ years without issue now -- I think it's probably safe at this point, especially if you can install from your package manager (as I can with an AUR helper on Arch).
"Enigmail works great here" that's good to know I never said it did not. We can agree to disagree about it being in mainline and receiving the same attention and support as the rest of thunderbird. I don't think your "+3 years" have really exposed you to all the growing pains enigmail has had.
I agree, Enigmail has been around longer than I've actively used it (for the record, I had installed it occasionally before, but hardly used it). The point I was making is that it seems to be stable and mature software now, and that maturity has existed for a reasonably long time. Surely there's not much point in holding a grudge against software with a buggy past; that'd severely limit the pool of available software...
