More exactly, it is listed in them as a conforming attribute.

That is correct. In the October 2012 version, it was not described as
conforming, and it eas explicitly listed as nonconforming:
“abbr on td and th elements
Use text that begins in an unambiguous and terse manner, and include any
more elaborate text after that. The title attribute can also be useful
in including more detailed text, so that the cell's contents can be made
terse.”
http://www.w3.org/TR/2012/WD-html5-20121025/obsolete.html#non-conforming-features

In the December 2012 version, this was taken back as regards the th
element. This has been the situation since that. That is, abbr is valid
for th, invalid for td (and any other element).

It should have just "td" there. HTML5 declares abbr as obsolete for td,
but not for th. (It declares td as purely a data cell, not at as data or
header+data cell, which was the HTML 4.01 position.)
