When setting up MySQL using the mysql_service block, there is an option called initial_root_password. When setting that to some specific string, I expect to be able to use that string to log into the server later.
In reality, I cannot use the password because the authentication is handled via Socket by default, ever since MySQL 5.7 I believe.

Steps To Reproduce
In a custom Chef cookbook, use this library and configure as follows:
mysql_service 'default' do
version '8.0'
charset 'utf8mb4'
bind_address '127.0.0.1'
initial_root_password 'super_strong_password'
socket '/var/run/mysqld/mysqld.sock'
action [:create, :start]
end
:police_car: Expected behavior
After Chef finishes, I can log in via mysql -u root -p and then entering the super_strong_password I defined above.
In reality, MySQL just reports Access denied for user 'root'@'localhost'
:heavy_plus_sign: Additional context
When forcing access to the console through sudo mysql, one can see that the server is actually configured to use the auth_socket plugin:
As far as setting the default password is concerned, I think it happens here. But this invocation has no effect if auth_socket is used, and MySQL reports a warning along the lines of SET PASSWORD has no significance for user 'root'@'localhost' as authentication plugin does not support it.
I am aware of https://github.com/sous-chefs/mysql/issues/539 but that issue never reached any actual conclusion. I'm curious to know why the revert that I mentioned above happened and if (and why) this is intended behaviour.

To make the password access work, the plugin must be changed upon setting the password. The

change was once properly introduced in https://github.com/sous-chefs/mysql/commit/9a66e575a16bfd448ed51f3970ad4eacc78e4413, but then got reverted immediately in https://github.com/sous-chefs/mysql/commit/fe39425e99f7fde2e11c82ac4c19ed05921f9e63 for unknown reasons.I am aware of https://github.com/sous-chefs/mysql/issues/539 but that issue never reached any actual conclusion.
