There are a lot of subtle changes when a subsystem is rewritten.
That's just how it works.
This change was implemented in a recent alpha:
"to better support unreliable networks and restrictive sets of entry
nodes"
https://gitweb.torproject.org/tor.git/tree/ChangeLog?id=ac04fcd2e758c2258cbde8c8f31586695cb5d666#n12
And it was fully documented in proposal 271:
https://gitweb.torproject.org/torspec.git/tree/proposals/271-another-
guard-selection.txt#n648
https://gitweb.torproject.org/torspec.git/tree/proposals/271-another-
guard-selection.txt#n114
And no, the earlier bug in almost all versions of tor was much harder to
debug. (I've debugged ReachableAddresses errors while implementing IPv6
support.) This fix will make it much easier.
