We have been gradually loosening constraints for replacing Tidy with Remex on wikis (see T182042 = 0, T184656 < 10, T188010 < 25).
As a next step, we are going to replace Tidy on all wikis that have fewer than 50 entires in all high-priority Linter categories.
I plan to make this switch on April 11 as part of the morning SWAT window. I'll make a list of all affected wikis next week, but, an additional 50-100 wikis will have Tidy removed during this step. The plan is to swith over all wikis by end of June.
The list of wikis that will be switched over are:
