There’s a lot of bikeschedding on how to use it in conjunction with the (also stage 1 proposal and forever delayed) pipeline operator[1] unfortunately. Add in never ending arguments on which symbol we should use (the questionmark has a lot of responsibilities already) and here we are.

To make matters worse it appear that generally OOP style darlings such as static class blocks and true private fields seem to gain more momentum.
