Description
Schema change backfills can become too disruptive at scale, so let's disallow them for now. Same with initial scans.
Jira issue: CRDB-55587
Epic CRDB-55919
Contributor guide
Research direction
Start by locating the changefeedccl implementation and the handling for database-level feeds. Trace how schema change backfills and initial scans are configured, then inspect nearby tests. Done means database-level feeds default to both options being off and reject requests that enable them, with coverage for those cases.
