In its favour: Exposing problems early, when they can easily be fixed,
is good.

To its detriment: Making the interactive interpreter behave differently
by default from the non-interactive interpreter should be resisted; code
which behaves a certain way by default in one should behave the same way
in the other, without extremely compelling justification.

I'm willing to hear more argument for and against.
