Hey André, This does indeed seem to cut into the traditional property accessors scope.
I'm no longer seeing a reason to have property accessors, since immutable state (and promotion thereof) is much more relevant to fight bugs and improve application performance and maintainability. Therefore, I would endorse re-visiting the RFC at https://wiki.php.net/rfc/write_once_properties instead. Máté also linked today ( https://twitter.com/kocsismate90/status/1277625002720968704) that C# 9.0 is getting init-only properties, which looks similar to the RFC linked above. Assuming we solve annoyances around cloning, that would be a more sensible way forward, while property accessors seem to perpetuate the bad practice of getters and setters, which are the main cause for me having to fire up a debugger in any environment.
