Comment (by dcf):

 Replying to [comment:7 gk]:
 > dcf/cohosh: how important is that for the decision about shipping
 snowflake in Tor Browser 9.5 stable? Should this work go into it if
 snowflake is picked for stable? Should it get more testing on alpha first?

 cohosh is right, there should not be a stable release without this ticket.
 The children of #19001 are some other things that may have to happen
 before a stable release, but for me, this ticket is the big one necessary
 for a good user experience.

 I intended this ticket to go into alpha first. There have been several
 test bundles made with it, but not much testing by people outside the
 anti-censorship team. Also, I'm not sure we currently have enough
 Snowflake proxies to support users of stable if it suddenly becomes very
 popular; i.e., I expect we could handle 1,000 users but maybe not 10,000
 at this point.
