We are late in the regression season, and it's clear that quite a lot of patches are still needed to fix all of the rendering and memory errors (all of 7063, plus at least one more to fix yet another bug in Multisim reported in bug 53706). In the event that those patches are not considered safe enough, simply reverting the entirety of transformed arc support is an alternative.
This does sacrifice one feature for another, but it's not clear that bug 34579 and 35331 ever affected a real application. Certainly they did not name any.
