I don't think it's remotely crazy. libCEED supports both together and it's very convenient when testing on a development machine that has one of each brand GPU and simplifies binary distribution for us and every package that uses us. Every day I wish PETSc could build with both simultaneously, but everyone tells me it's silly.
