I have not yet added this back in.
Its a tricky topic.
Various page settings means worse google results and sharing of links dont work well ( your page 200 is someone elses page 20). You copy and past the address bar and it will be wrong.
I can add this back in. Its mostly at the expense of some search engine optimization. I dont like that. There are some peformance and cashing issues too. But less so.
Sooo, can we finds a happy medium first where we simply set the length?? What do you want to change it to?
Or are there so many different wants between users that's its worth that SEO hit?
