Sorry, I was answering the wrong question.

In fact, on an update, yes, we probably will update everything to the
highest revision we possibly can. The cost of the local entries files
rewrites is outweighed by the reduced network traffic later, when we
have fewer exceptions to report in most directories.

Anyway, this seems reasonable to me... I mean, we did update those
things, so we should record the new up-to-date information somewhere,
right? The fact that recording it incurs some bookkeeping is only

In any case, if we don't update them, the price is simply that
state-reporting grows more expensive over time. I like
trade-offs... They feel like evidence that real work is being done,
and that someone has to pay for it. :-)
