Bitcoin Inquisition recently had a PR about soft fork activation and as part that PR, it buries taproot and references a closed PR to Bitcoin Core to bury taproot. Will the taproot deployment be buried in Bitcoin Core and if so, what needs to be in place to bury it?
The Taproot deployment is buried insofar as consensus no longer checks its status to determine whether to enforce the Taproot rules. The Taproot rules are enforced from genesis now, with the (hardcoded) exception of a single block.
Burying is generally for a performance improvement resulting from not needing to constantly check the deployment status. Since Taproot rules are always used, there's no need to specify a buried deployment height nor to remove the deployment parameters, and so the deployment parameters remain. The deployment code is only called when users use
getdeploymentinfo, and in that case, it may be useful to have the historic deployment information rather than stating that it is buried.
