The top priority is "the show must go on."
Putting a trusted DI first in the signal chain (between the bass and the amp) guarantees that the show can keep going, even if my amp dies, or my cabinet dies, or the 9v battery in my effect pedal dies.
Even if I was planning to mic the cabinet and use a 100% "wet" signal, I would still want that DI as a safety net.
This is one of the reasons good engineers like to use a stand-alone DI, as opposed to (or, in addition to) the DI from my amp.
