Attention needed from Roger McFarlane

Message from gwsq

From analysis/uma/chrome-metrics.gwsq:
Histograms should by default be reviewed by the owners of the subdirectories. The chromium-met...@google.com gwsq should be used when there are no individual owners, or for escalation to the Metrics team.
If you are interested in becoming a metrics reviewer, please review the instructions at https://chromium.googlesource.com/chromium/src.git/+/HEAD/tools/metrics/histograms/README.md#Becoming-a-Metrics-Reviewer

Commit message:

Delay expiry of frequently used histograms.

Updates the expires_after attribute for 880 histograms that show
frequent access in the past 180 days.  These are the 99% most
frequently used histograms over that time that have an expiry date
(or milestone equivalent) between 2026-04-24 and 2026-07-08.
