It depends on what and where you are flying.
I'd say engineering is required to survive an encounter with a hostile CMDR. It pretty much has been ever since engineers were introduced, but over time players found ways to kill more effectively (feedback rails, long range PAs, massed frag cannons or packhounds, corrosive weapons) and make it more difficult to escape (FSD disruptors, drag munitions) or fight back (TLB, force shell, dispersal field).
These days if you fly a relatively slow ship (and all unengineered ships are slow compared to engineered FDL), there are ways to make it impossible to high wake quickly and you need to be able to tank several thousand HP worth of incoming damage - which is difficult (and on most ships outright impossible) without engineered hull and shields.
