----------------
I think "state change", "client information" and "requesting it" might be a bit too vague.
Some ideas to take or leave...

"onSemanticsMaybeChanged"

Called when the meaning of a source code may have changed without an edit.
Usually clients assume that responses to requests are valid until they next
edit the file. If they're invalidated at other times, we should tell the client.
In particular, when an asynchronous preamble build finishes, we can provide
more accurate semantic tokens, so we should tell the client to refresh.
