Warning (lsp-mode): Unknown notification: metals/syncStatus

[Rogach]

Describe the bug
Upon starting lsp-mode in a Scala file, warning "Unknown notification: metals/syncStatus" is displayed.

To Reproduce
I'm using lsp-mode 20260112.1722, lsp-metals 20250228.2145, metals 2.0.0-M7. Using BSP to connect to Mill.

Logs
Notification as seen in the lsp logs:

[Trace - 04:46:37 ] Received notification 'metals/syncStatus'.
Params: {
"document": "file:///modules/main/src/SomeFile.scala",
"status": "hidden"
}
[Trace - 04:46:38 ] Received notification 'metals/syncStatus'.
Params: {
"document": "file:///modules/main/src/SomeFile.scala",
"status": "untracked",
"kind": "warning",
"text": "$(alert) Untracked",
"tooltip": "Document is not synced with build server. Click to sync.",
"command": "metals.sync-file"
}

I've worked around it for now by adding

("metals/syncStatus" (lambda (&rest args) nil))

to :notification-handlers in

lsp-metals/lsp-metals.el

Line 874 in e1d9d04

:notification-handlers (ht ("metals/executeClientCommand" #'lsp-metals--execute-client-command)
