Comment:

 Most clients use microdescriptors and the microdescriptor consensus, so
 the size of fingerprints in descriptors doesn't matter that much.

 Microdescriptor fingerprints have always been base64:
 https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n1563

 As have v3 consensus and microdesc consensus relay line fingerprints:
 https://gitweb.torproject.org/torspec.git/tree/dir-spec.txt#n2297

 And any fingerprints in tor cells are binary.

 There are a few fingerprints that are still in the legacy hex format, but
 their space usage is insignificant compared to 6000 relays.
