None of these arguments are really specific to ERT. It just seems like
you like to run with debug-on-error, which is fine (I do too).
But don't impose it on all ERT users.

You're right, sorry: brain malfunction.
But that just means you first have to fix the bug that signals "a" before
getting to the bug that signals "b".
