This is just an initial guess, but this is probably because the CommandMap is no longer used for executing commands, the brigadier dispatcher is. And they are only synced when CraftServer#syncCommands() is called. which is once after plugin loading, and during a reload.

This change was made (purposefully, I think) by spigot for 1.19.1

I can confirm this bug with LibertyBans' command aliases. Command registration fails to have effect after the startup process.

Command unregistration also fails. Unregistering a command has no effect, either.
