Not necessarily, no. Content warnings were implemented in Mastodon specifically as summary
plus sensitive
=true
. Perhaps not originally, but that is enforced now (all CW'd posts from Mastodon are marked sensitive). Might be Mastodon will CW notes that don't have sensitive
, out of caution, but this doesn't apply to non-Notes.
So a summary included in a non-Note is not CW'd by Mastodon currently.
I suppose, although in that scenario theoretically one could add
as:sensitive
to mark the status as CW'd? I don't think CW logic is even run for non-Notes at the moment, though I could be mistaken.
