The tag alias #15788 macedonian_flag -> sunburst_background has been rejected.
Reason: As per the Prespa Agreement signed between Greece and the former Yugoslav republic (now renamed North Macedonia), effective yesterday (Feb. 12). Just found this out in Wikipedia.
EDIT: Better yet, we might have to think of a better tag name since the current tag describes a sunburst background rather than the actual flag. Any thoughts?
EDIT 2: Changed alias destination proposal to a more descriptive one, although I'm also thinking "rising sun" will somewhat overlap with this concept.
EDIT 3: Deleting the request to facilitate the mass edit, though some more discussion for a better tag needs to be done.
EDIT by DanbooruBot: The tag alias macedonian_flag -> sunburst_background (forum #154704) has been rejected by @nanami.
