Comment (by karsten):

 You mean something like this?

 (I can turn this into a real commit with changes file if this is the patch
 you want to apply.)

 This patch is certainly simpler.  But it has the downside that directory
 authorities will have to include "caches-extra-info" forever, or at least
 until we teach clients not to rely on that line plus two or three release
 cycles.  (That's why I suggested 0.2.5 above, to save a release cycle.)

 If either patch is too hot for 0.2.5, how about we defer until 0.2.6?
 Nothing urgent here.
