Comment (by karsten):

 Here's another option: rather than append multiple descriptors to a single
 flat file we could produce a tarball containing the few hundred or
 thousand descriptor files. Basically,

   `https://collector.torproject.org/recent/relay-descriptors/server-
 descriptors/2020-03-10-14-05-00-server-descriptors`

 containing 596 descriptors concatenated to a 1.4 MiB file would then be
 replaced by

   `https://collector.torproject.org/recent/relay-descriptors/server-
 descriptors/2020-03-10-14-05-00-server-descriptors.tar`

 containing 596 descriptor files.

 Advantage over the approach sketched out above would be that we wouldn't
 have three output file formats anymore (flat file with 1 descriptor, flat
 file with >= 1 descriptors, tarball). Disadvantage might be that
 processing tarballs can be less convenient than processing flat files.
