Comment:
I just did a spot-check on some large extra infos.
The largest one I found was about 4.5 KB, and Tor's limit is about 48.5
KB.
So I think 10x is an appropriate safety margin for the next 3 years.
(The biggest contributor to the size is the country list and client
numbers. Each of ~250 countries can potentially take up 4 + log(client
count) bytes. Even with a million clients per relay, that's only an extra
2.5 KB.)
