PR #1084 (antalya-25.8) set these defaults to true. This override was not forward-ported to antalya-26.1, so they reverted to the upstream default (false).
Action required: forward-port PR #1084 to antalya-26.1 to restore datalake catalog defaults to true.

allow_* settings (A-CHG): PR #1084 override was not forward-ported to antalya-26.1. Action required: forward-port PR #1084 to antalya-26.1 to restore datalake catalog defaults to true.
- 4 new Antalya settings (A-NEW): expected additions from PRs #1402, #1453, and #1490. No action needed.
- 3 outdated-snapshot settings (A-SNP): already present in Antalya 25.8 but missing from the snapshot. Values unchanged in 26.1. No action needed.
- All other diffs: upstream changes (U-CHG, U-NEW, U-ADD). No action needed.
