 > Uncompressed microdescriptors get 7% longer. Compressed microdescriptors
 get around 12% longer. This shouldn't matter even ''that'' much if we are
 right that microdescriptors change infrequently, and consensuses dominate
 the amount of stuff we download.  We can get it back down to 0% later on
 when we implement proposal 228.

 Those numbers assume that we include 160-bit identity digests in
 microdescriptors.  If we're feeling cheeky, and we decided to include a
 128-bit truncated digest, the uncompressed and compressed overheads are
 6.7% and 10% respectively.  If we dropped to 80 bits, we'd add 5% and 7%
 respectively, but I should never pay attention to the "80 bits are enough"
 voice again.

 (All these numbers were obtained by adding random id lines to all the
 microdescriptors in my cached-microdescriptors file)
