I've got this:
"pagelinks pl_from index-mismatch-prod-extra": { "s4": [ "db1141.eqiad.wmnet", "db1121.eqiad.wmnet", "db1148.eqiad.wmnet" ], "s6": [ "db1098.eqiad.wmnet", "db1096.eqiad.wmnet" ] }
It's likely similar to T252126: tl_from index on templatelinks is lingering in production and leftover from T174509: Drop now redundant indexes from pagelinks and templatelinks
