I don't know if it is necessary for ordinary bridges to expose the
ORPort. For a long time, it was necessary, because BridgeDB used the
ORPort to check that a bridge was running, before distributing it to
users. See:
https://bugs.torproject.org/tpo/core/tor/7349
But now there is rdsys and bridgestrap, which may have the ability to
test the obfs4 port rather than the ORPort. I cannot say whether that
removes the requirement to expose the ORPort.

For the special case of the default bridges shipped with Tor Browser, it
is not necessary to export the ORPort, because those bridges are not
distributed by rdsys.
