I've seen plenty of bridges, both plain-vanilla and obfs4, with or without IPv6, regardless of geography, that use only a few megabytes of bandwidth per month. Everything seems good in terms of connectivity yet there is basically just housekeeping traffic. Some bridges just seem to go ignored as entry points into the Tor network.

Bridges are allocated to users at random (and some are randomly chosen
to be reserved). So they might not be used. You can set up 2 bridges per
IPv4 address, and you can give them an IPv6 address, too.

In contrast, all Tor clients see all tor relays, and choose paths at
random. So all tor relays are used according to their bandwidth weights.
