Some engineering solutions have purely business justifications.
For example, take a look at the Tesla Model X and its Falcon Wing Door. It is very clearly a stupid design from an engineering perspective, but is sufficiently unique to have its own name. It also very obviously draws everyones attention when used and draws attention to the product which further promotes it. So while everyone else has normal doors ... you have special doors. On top of that, the owner can say that they have an SUV without those pesky mini-van doors which obviously work better, but then you're driving a mini-van.
Similarly, while everyone else is using a vanilla database that does its job and warrants no special attention ... we're using blockchain! We're new, we're special, etc.
It's marketing, not engineering.
