Just shows how far certification requirement dropped by the time of TNG. Nowadays, no Starfleet ship design would be certifiable.
Obviously joking, but the reason for this in TNG, as it is for cars, that it was cheaper. The same reason RBMK reactors are graphite moderated with a positive void coefficient.

Well, see also the lifts; I’m pretty sure that over the course of the series the Enterprise alone had more catastrophic lift incidents than most _countries_ today have in like time. And the consoles which explode whenever anything happens. And the _bloody holodeck_. Clearly, at some point in the next century, some catastrophe kills off engineering as a discipline entirely.
