As a counter proposal that (I hope) would get broader consensus,  I suggest to 
just do this for 'emit': QTBUG-82379 .

I don't think this is exactly a counter proposal for the plan or the scheduling posted by Marc, though. We're now bikeshedding about Q_EMIT vs [[qt::emit]] vs. qEmit or anything.


Can we instead discuss about the plan instead? AFAIU it could be simplified as:

* Qt 6.x
** Introduce opt-in ways to request lowercase keywords: -DQT_USE_KEYWORDS, CONFIG+=keywords, whatever. They do nothing.
** Default for user projects is still same as today (use lowercase).
** User projects get a deprecation warning unless they specify no_keywords and/or keywords. Specifying both keeps keywords.

* Qt 6.[x..x+3]
** Qt turns on no_keywords for itself (all code, examples, docs).
** Nothing changes for end-user code.

* Qt 6.(x+3)
** Default for user code becomes no_keywords.

Am I reading the original proposal correctly? The (x+3) here means that there'll be at least one LTS in the middle where behavior won't change for end-user applications.
