The bug

Since Minecraft version 1.19 the proxiedplayer.chat() function no longer seems to work.
When you use it on the latest server versions it always creates an error like this:

[13:54:31 WARN]: Error in dispatching command
java.lang.UnsupportedOperationException: Cannot spoof chat on this client version!

One year ago someone mentioned this bug and md-5 said that chat spoofing is no longer supported. (#3327)
Other than that I couldn't find any info anywhere that this function should no longer be used.
After one year the chat function is still added with no warning of it being broken since 1.19+.

My request:
Could you either make the proxiedplayer.chat() deprecated or add a warning in the function documentation to no longer use it in the latest versions? Otherwise people will continue to have a hard time when trying to use that function and not knowing about the chat signing change in 1.19.

Checking

• I am using BungeeCord and not a fork. Issues with forks should not be reported here.
• I think this is not an issue with a bungeecord plugin.
• I have not read these checkboxes and therefore I just ticked them all.
• This is not a question or plugin creation help request.

Given the issue is javadoc related, I do not see a problem asking the user to just actually edit it himself.
