The QtCS24 misses the single one big reason you want to switch C++20 now and whenever possible: Concepts. They indeed are a total game changer and I'd boldy predict that 80% of all meta-programming helpers in Qt's headers could be replaced by concepts that are easier to understand, more expressive, more complete. You simply do not like C++ if you are not eager to use concepts.End of the advertisement block.
This has been discussed at QtCS. The problem is that this would "just" imply an easier development of Qt itself, but not necessarily a better development *with* Qt, as we don't really expose concepts as public APIs. Does that convenience of development for ourselves outweigh the market for platforms that are limited to C++17?
