Comment(by rransom):

 Replying to [comment:4 Sebastian]:
 > The situation I want to avoid is that we hear advice like "oh, hs
 doesn't work for you? Just newnym for good measure" because we should only
 advice newnym usage when the user actually wants a new nym.

 We already use NEWNYM to stop using a circuit whose exit node is flaky,
 misconfigured, evil, or otherwise broken, and to clear ‘enough’ client
 state between tests in a Torperf run.  Having NEWNYM break users' Tor
 clients will not make us stop recommending that users use it for reasons
 other than making future Tor streams unlinkable to previous streams.

 See #3335 for a ‘never make users use NEWNYM to fix this if NEWNYM didn't
 break it’ ticket, but this change is still needed because (a) it is
 definitely simple enough to be merged directly to maint-0.2.2, (b) it is
 needed to keep NEWNYM from breaking things, and (c) it is needed for a
 hidden-service analogue of Torperf.
