Please add editcontentmodel access to the templateeditor group on testwiki
This is for use case validations related to T85847 and linked tasks (the 'make sure nothing blows up (a week or two after announcing)' part)
Stemming from enwiki discussion at: WP:VPT#Should moving a page change its content model in some situations? (archive)
Note, per usual - there isn't a "community" at testwiki. This access is already present on administrators, but we specifically want to be able to test use cases where the rights holder is not an admin.
