I totally agree with you that a retrofitted bitcoind is not an industry grade solution. But it is a relatively quick way to perform R&D and deploy pilots, and this at least is how we position and market our own tool in the space.
In my view an industry grade blockchain will simply be a piece of middleware that manages security, synchronization, validation between a set of distributed relational databases. It may even end up being a feature of RDBMSes themselves. I like the bitcoin transactional model (= distributed MVCC) because it lends itself very naturally to this eventual model.
