You may want to observe how actual IRCds in the wild behave. The channel creator status -- even the entire !channel thing -- just generall does not exist nowadays.

• +a is an extreme rarity and usually instead used to denote channel admin (prefix &, usually used in combination with +q/~ for owner).
• +q is similarly unused nowadays or rather got repurposed for another channel user status.
• +r is usually used to denote channel registration with services instead. Due to !channels not existing, it's fairly whatever.
