Probably the simplest option is to use structured dtypes, which should already work with the existing version of xarray, e.g.,

Thanks, that's a nice trick! Supporting da.x_bounds['start'] will definitely be helpful!

However, I am still concerned about 2D boundaries. Using the structured data type, 2D bounds will be an array of size (Nx,Ny,4) instead of (Nx+1,Ny+1). Although this matches the CF convention, it takes 4x memory and needs to be converted back to (Nx+1,Ny+1) for pcolormesh(). Not a big problem though. I will be happy to go this way if (Nx+1,Ny+1)-sized bounds cannot be implemented.
