A - node that may be left by pedestrians in at least two directions. Naive check for eligible ways: highway=footway or highway=path or (highway=cycleway and (foot=yes or foot=designed))
B - node that may be left by cyclists in at least two directions. Naive check for eligible ways: highway=cycleway or ((highway=path or highway=footway) and (bicycle=yes or bicycle=designed))

Those "missing *=crossing" test ticket should be fixable with our Help/Validator/MapCSSTagChecker by using Help/Styles/MapCSSImplementation#Parentselector. Since custom MapCSS tagchecks can be added in the preferences, creating such tests does not require a development setup. We're happy to get patches.
