Relays without descriptors are not scaled, but still added to the bwlines without vote=0
As can be seen in: https://gitweb.torproject.org/sbws.git/tree/sbws/lib/v3bwfile.py?h=maint-1.1#n1317
As a result, some relays (in sample data counted ~800) are included in the bandwidth file without its bandwidth scaled, which could be quite different (higher or lower) than the scaled bandwidth.
This is one of the several reasons of #33775 (moved).
