Implemented in WebKit/Blink, documented as an IE extension, although IE11 no
longer supports it.

Usage is ridiculously high:

Cost of support is low:
bool legacyReturnValue() const { return !defaultPrevented(); }
void setLegacyReturnValue(bool returnValue) {
setDefaultPrevented(!returnValue); }

Consider spec'ing this?
