I think we might be in a period now (with the Tories bust and Corbyn as secure as he can be at the LP helm) where we see Corbyn edge toward institutional "respectability" on some issues. He's already turned his leadership toward being a champion for manufacturing capital and I reckon we'll see some softer approach towards policy sacred cows. Corbyn/McDonnell are within touching distance of No.10 and they are parliamantarians above all, not revolutionaries.
A point so often over looked
