In reply to Poen Ponis.

Thanks a lot for this & the following comment Poen 😍. I was to suggest jumping to 5.9 as both are around 5% of « WordPress installs shares », but I felt it could be interpreted as being a bit pushy. We made a first step in 10.0 to avoid loading our Styles & Scripts everywhere (filter hook to opt-out), you reminded me we had to make the 2nd step during 12.0 (filter hook to opt-in). I’ll réa-add the ticket to Milestone 12.
