And why would they apply a workaround to some things and not others?
As John said, some workarounds will fix the problem and not cause others, while other workarounds may cause additional problems not related to the original.
Even if they are right, it would be sensible to either work around it or provide information as to what the bug is so that other people might be able to fix it, or encourage it to be fixed.
True... but for us, it's not a big enough issue to concern ourselves with at this time.
