Profile event handlers are not being called

[paaulhier]

Expected behavior

Event handlers for events in the com.destroystokyo.paper.event.profile package should be called whenever a client attempts to connect to the server.

Observed/Actual behavior

ProfileWhitelistVerifyEvent event is handled (aside from the expected case of an offline client), but FillProfileEvent, LookupProfileEvent, PreFillProfileEvent or PreLookupProfileEvent are never handled.

Steps/models to reproduce

Create a new plugin called "LookupTest".

paper.yml:

name: LookupTest
version: @version@
main: com.kwvanderlinde.lookuptest.LookupTest
api-version: 1.16

LookupTest.java:

package com.kwvanderlinde.lookuptest;

import org.bukkit.plugin.java.JavaPlugin;

public final class LookupTest extends JavaPlugin {
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(new Listener(getServer()), this);
    }

    @Override
    public void onDisable() {
    }
}
Listener.java:

package com.kwvanderlinde.lookuptest;

import com.destroystokyo.paper.event.profile.*;
import org.bukkit.Server;
import org.bukkit.event.EventHandler;

public class Listener implements org.bukkit.event.Listener {
    private final Server server;

    Listener(Server server) {
        this.server = server;
    }

    @EventHandler
    public void onPreLookupProfileEvent(PreLookupProfileEvent event) {
        server.getLogger().warning("PreLookupProfileEvent");
    }

    @EventHandler
    public void onLookupProfileEvent(LookupProfileEvent event) {
        server.getLogger().warning("LookupProfileEvent");
    }

    @EventHandler
    public void onFillProfileEvent(FillProfileEvent event) {
        server.getLogger().warning("FillProfileEvent");
    }

    @EventHandler
    public void onPreFillProfileEvent(PreFillProfileEvent event) {
        server.getLogger().warning("PreFillProfileEvent");
    }

    @EventHandler
    public void onProfileWhitelistVerifyEvent(ProfileWhitelistVerifyEvent event) {
        server.getLogger().warning("ProfileWhitelistVerifyEvent");
    }
}

Add the plugin to a fresh server folder:

> find . -type f
./server-1.16.1.jar
./plugins/LookupTest-1.0-SNAPSHOT.jar

Start the server.

Now connect with a client (online and offline) and see which events get logged.

Plugin and Datapack List

None beyond the LookupTest plugin

FillProfileEvent and PreFillProfileEvent are indeed never called since 1.21.9. PreLookupProfileEvent is called for the fetchprofile command for example but maybe some case are missing, LookupProfileEvent seems to be only called for legacy files upgrade.
