10 years ago, in another life, I was already experimenting with trying to provides feature from moc with reflections and from other macros:

- https://woboq.com/blog/reflection-in-cpp-and-qt-moc.html 2014, That was based on a previous reflection proposal

- https://github.com/woboq/verdigris : 2016, Replaces the moc by a set of macros.

What my verdigris experience shows is that it is perfectly possible to replace the moc at the cost of slightly uglier macros. And this was using C++14. I haven't look in details at the C++26 reflection, but I'm sure it would make it easier to make these macro more pretty.
