I think bit_cast may finally solve the last major use case of reinterpret_cast (building type safe memory mapped device objects) but I haven't sat down and tried to verify this yet. Unfortunately there are also still a lot of platforms that have yet to get C++20 support and memcpy is not a viable alternative. Hopefully this is less of an issue in the future as major MCU orgs like TI have started switching to LLVM/Clang based compilers which can follow upstream with little to no changes needed. Edit: I just did some digging and bit_cast does not work for the aforementioned use case since it can copy the data to a new location in memory. This prevents us from being able to reliably use it to write to memory registers.
