I chose option #1 (it's clearly canon, and it's at least provisionally prime), but I also lean strongly toward #3 (it may ultimately reveal itself to be close-but-no-cigar).
That said, in my headcanon I don't think of the "prime timeline" as a single integrated whole. I keep planning to start a longer thread about this one of these days, but for the moment suffice it to say that I'm in the camp that thinks Trek has had enough time-travel shenanigans over the years that the version of "prime" from which the Abrams movies were shown to branch off isn't necessarily the same version we were seeing in any particular past series.
It's close, but there are differences. This makes it easier to rationalize at least some of what DSC has thrown at us.

Oh, hell no. TOS is Star Trek, period. It is the ur-canon. It is the original from which all others followed. If something in some later production is irreconcilably at odds with the original, then in my book the original wins. Every time.But seriously, I decided in my teens (having already seen lots of TOS before TNG started in the UK) that TOS might be the spirit of Trek, but large portions of it needed to be ignored as "apocrypha" in order for it to make sense as one timeline.
