WordPress Performance Trac tickets

@westonruter shared the current 6.9 milestone tickets and noted that the fetchpriority support PR #8815 still needs a maintainer review+approve. Once merged, work can proceed on the related #63486.
@westonruter also asked if someone more familiar with Opcode Caching could review this PR #9260, which adds Site Health information.

@westonruter announced that the next Performance Lab release will include an admin pointer for the View Transitions plugin PR #2122.
- @b1ink0 asked whether to release Performance Lab now or wait until PR #2059 is ready, as it needs a round of review. @westonruter suggested waiting so that the release can go out next week before WCUS.
@westonruter also noted that the admin pointer should be omitted if View Transitions is already active (Issue #2136) and mentioned PR #2119, which proposes adding the No-cache BFCache plugin as a new feature to Performance Lab.

@westonruter suggested that the next office hours will coincide with WCUS Contributor Day and could be repurposed for contribution and shift it later perhaps. Or have it be more open-ended for the day.
