You mean if it is not yet the case?
My point is:
- It looks weird that “Twitter” emojis are explicitly stated deprecated in the list, while they are still the default, i.e. the “reset” button in our case still applies these deprecated Twitter emojis.
- So I was wondering whether the default has really not changed in upstream code, along with renaming “Twitter” to “Twitter (deprecated to Twemoji)”, or default settings changes do not apply retrospectively to existing Discourse instances. In this particular case I see an argument to not change the default on an existing instance, so admins can always revert to what their forum was shipped with, and settings they never touched do not change without them explicitly changing them.
- Other wording: Do the “reset” buttons apply the Discourse defaults (which may change), or do they apply whichever value the Discourse instance was originally shipped with?
Well, I guess the default has really not been changed yet, the other theory seems quite complicated behavior
