FYI: Chrome is going to ship 'appearance' property soon. https://t.co/osaFPo0Obe
FYI https://bugs.chromium.org/p/chromium/issues/detail?id=963551 is now fixed and looks like it's targeting M84 (reaching stable mid-July per https://www.chromestatus.com/features/schedule ) I think trying to coordinate on the timing on this can reduce compat problems, and allow for clearer messaging to web developers to start using unprefixed appearance.
