+Subject: [PATCH] Break up and make tab spam limits configurable
+
+Due to the changes in 1.13, clients will send a tab completion request
+for all bukkit commands in order to factor in the lack of support for
+brigadier and provide backwards support in the API.
+
+Craftbukkit, however; has moved the chat spam limiter to also interact
+with the tab completion request, which while good for avoiding abuse,
+causes 1.13 clients to easilly be kicked from a server in bukkit due
+to this. Removing the spam limit could cause issues for servers, however,
+there is no way for servers to manipulate this without blindly cancelling
+kick events, which only causes additional complications. This also causes
+issues in that the tab spam limit and chat share the same field but different
+limits, meaning that a player having typed a long command may be kicked from
+the server.
+
+Splitting the field up and making it configurable allows for server owners
+to take the burden of this into their own hand without having to rely on
+plugins doing unsafe things.
