Hallo Amir Ladsgroup:
The main thing against your proposition is compatibility: 1-PWB is designed to work in ALL wikis and so many of them are not WMF-related and even don't have any SSL connection ability 2-Iran and Chinese people are excluded for SSL and They can't run bots anymore if we use just SSL
I'm not sure why you're telling me this, my question/suggestion had nothing to with with en- or disabling SSL for any number of people - in fact, that decision seems to have been made already by other people.
