I don't think we have telemetry on that... We can probably add one, but I'm not sure where is the best hook point of it. Is there telemetry for any other attribute I can take as a reference? A note is that ParseFragment's internal usages would need to be carefully excluded from the telemetry. - Xidorn _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
