  It has been argued that the observational limits on a supernova (SN)
associated with GRB060614 convincingly exclude a SN akin to SN1998bw as its
originator, and provide evidence for a new class of long-duration GRBs. We
discuss this issue in the contexts of indirect 'redshift estimators' and of the
fireball and cannonball models of GRBs. The latter explains the unusual
properties of GRB060614: at its debated but favoured low redshift (0.125) they
are predicted, as opposed to exceptional, if the associated core-collapse SN is
of a recently discovered, very faint type. We take the occasion to discuss the
'association' between GRBs and SNe.
