Over at Bardiac, there's a fine round-up of the blogospheric response to Michael Berube and Jennifer Ruth's proposal for a teaching-intensive tenure-track. (http://bardiac.blogspot.com/2015/06/metablogging-conversation-about.html?m=1) Yes, it quotes the Good Enough Professor, which makes this post meta-meta-blogging.
If anecdotal data like mine suggests a general trend towards creating some middle ground between tenure and rank exploitation, that seems like a good thing. Non-exploitative working conditions are better than exploitative ones. There's a bigger problem, though. Without provisions for academic freedom, shared governance, and grievance procedures these improvements will hasten the decline of higher education. Instructors who, however well-paid and professionally validated, are beholden to the administrators who hire them and not the faculty peers qualified to evaluate their teaching and research, will not sustain the mission of higher education as many of us understand it.
