You can now enable Cirrus as a beta feature on all wikis on which Cirrus is a secondary.  On English wikisource the link is https://en.wikisource.org/wiki/Special:Preferences#mw-prefsection-betafeatures.  The name of the feature is "New search" for now.  Yup, we know that it won't be "new" for too long but we hope that it'll become the standard search before it stops being "new".

Great news! 
I was afraid that with the previous option, not many users opted to test it, feeling bored to change the url with every search. As a beta featured they will be testing it with *every* search. This is very useful and nice approach on testing new features.
