In the absolute majority of cases users won't see any of that anyways, since
they'll use the register!() macro generated types.
// Master Control Register (MCR)
//
// Stores the offset as associated constant.
let mcr = regs::MCR::default();
// Set the enabled bit.
mcr.enable();
// Write the data on the bus.
//
// Calls `io.write<Self::OFFSET>(self.data())` internally.
mcr.write(&io);
For indexed registers it is indeed a problem though.
