Bitcoin Core PR #34419 exposes BIP54 fields in GBT
Bitcoin Core PR #34419 extends `getblocktemplate` so BIP54-related `lock_time` and `sequence` values can be included in BIP22 block templates.
The relevant mechanism is tooling compatibility: mining software consuming templates can see and use these constraint fields when constructing candidate blocks, alongside related mining-code handling documented in Bitcoin Core PRs and the BIPs PR.
Caveat: this is not evidence of version-bit signaling, protocol activation, ecosystem-wide miner behavior change, or changed miner incentives; the evidence only shows RPC/template exposure and related code/spec work.
