I guess it depends on what you work on. Both of my primary Rust projects (a .NET metadata parser & a Game Boy emulator) are heavily dependent on macro usage, and they implement multiple new macros. Both do lots of binary parsing, so I use bitflags, enum_primitive and bitfield all the time. For instance, I use this [1] two-macro monstrosity to parse tagged unions from the CLR metadata.
