Hi In [1], I mentioned the intent to unship <math>'s mode attribute. In bug 1548524, I'll intend to unship the remaining attributes deprecated in MathML3: fontfamily, fontweight, fontstyle, fontsize, color and background.
Actually, these have been deprecated since MathML2 [2] (released 16 years ago) and we have been sending deprecation warnings since Mozilla 20 (released 6 years ago). The MathML CG agreed to removed them from MathML Core [3] and Igalia does not plan to implement them in Chromium. Contrary to the mode attribute, these attributes are also implemented in WebKit [4] and we got bug reports about some of them in the past [5]. Hence, it makes sense to be a bit more careful. For now they will only be disabled in nightly and use counters to determine how much they are used.
