edit (April 14th 2021)
Jeremy Rubin has asked me to add the following:

"[bitcoin/bips#1104](https://github.com/bitcoin/bips/pull/1104) has been proposed (and implemented via
[bitcoin/bitcoin#21377](https://github.com/bitcoin/bitcoin/pull/21377)) as a concrete interpretation of @harding's original 
proposal. Feel free to re-ACK on the BIP PR (and in the core PR if you feel qualified to review) if this plan matches your 
expectations, or raise any concerns otherwise."

I'm going to rescind my ACK for Speedy Trial.

Agreed, if the Core Speedy Trial PR #21377 can get merged I think we should work around that.

Not trying to troll. I understand you are frustrated. But is it a final NACK or ACK?

@Rspigler: I personally won't be issuing any more ACKs or NACKs related to Speedy Trial, here or on Core PRs. I have tried to advance Speedy Trial in good faith (e.g. looking over the PRs and identifying that not only had we agreed on revised BIP 8 in the community meetings but a majority of reviewers had a slight preference for consistent use of block height) especially when I recognized that Speedy Trial had more community consensus than either BIP 8 (LOT=true) or BIP 8 (LOT =false)). Had I known at the time that there would be "NACKs of technical minutiae with very weak rationales, community meetings to discuss technical minutiae, coin flips...) over BIP 8 vs 9 and block height vs mix of block height and MTP for Speedy Trial" I would have NACKed Speedy Trial from the beginning.

I understand why Luke is angry and he should be. As he says Speedy Trial was supported by him (and me) because it had more consensus than either BIP 8 (LOT = true) or BIP 8 (LOT=false). For a small number of contributors (2?) to NACK using block height consistently across Speedy Trial and insist on not using BIP 8 is just bizarre to me in the context of where we were pre Speedy Trial and in the absence of a strong rationale to NACK using block heights consistently (test networks are not a strong rationale imo and nor is UASF marketing).

I am personally reviewing #21377 because I want to be as familiar with it as I can be and there is a very unlikely chance I find a bug etc in the code. But I won't ACK or NACK the PR and I won't issue any further ACKs or NACKs on this gist. I risk damaging my reputation (more than I already have) and making a mockery of the Core review process. In the very unlikely chance I find a bug I will of course raise it immediately.

For additional context see this and this from @maaku. He is staying out of this as he has quantum security reservations leading to him NACK Taproot itself. Regardless he writes better than me on BIP 8/9 and block height/mix of block height and MTP. He is also an author of a BIP on MTP.

bitcoin/bips#1104 has been proposed (and implemented via bitcoin/bitcoin#21377) as a concrete interpretation of @harding's original proposal. Feel free to re-ACK on the BIP PR (and in the core PR if you feel qualified to review) if this plan matches your expectations, or raise any concerns otherwise.

@michaelfolkson perhaps update the top post to point people appropriately
