Human meaningful witness versioning

In a recent discussion about Bitcoin Improvement Proposals (BIPs), Ava Chow clarified a misunderstanding regarding BIP 173, particularly about the bech32 component and its exclusion of the OP_PUSH32 operation. This correction significantly impacts the development direction of BIP 360, leading to a pivotal adjustment where Witness version 2 will be used instead of the initially planned Witness version 3. This change is documented in a pull request on the official GitHub repository for Bitcoin BIPs, which can be reviewed here. This adjustment underscores the dynamic nature of Bitcoin's development process, reflecting how community feedback and clarifications can lead to substantial shifts in technical strategies.
