I'm not sure if that's a convincing use-case. Inexact quaternions would arguably be more useful due to their use in 3D graphics, and I don't see them getting mandated in the numeric tower. It seems more reasonable to put the limit on inexact complexes, if just due to existing adoption. (FWIW I'm leaning towards voting no to all and asking them be optional modules like everything else, as Peter Bex suggested.)
