I do think that we still need one more generation of battery and FC improvements in weight/volume/size for these to be commercially viable, but it's nice to have one available to the public as opposed to the commercial-only PHFCEVs like the Kangoo Z.E.
I don't agree with the "excess bulk" assessment. an FC stack, plus radiator, plus H2 tank occupy space that would've been used by the batteries. there's no benefit there. it's just a trade-off made strictly for the benefit of fast refilling.
the FC-PHEV is just an interim solution for those with that particular need. by the time batteries get to a level you're happy with, they'll be dense enough that a 10%-80% charge will get you 250 miles range in just 15 mins, and in a volume that's smaller than an FC system. that renders FC's pointless by then.
