the only reason you do these in individual steps is that you need to
pass different flags, or are there other reasons?

Have you tried putting the pragma {-# LANGUAGE Safe #-} as the first
line into the submission file? I’m not sure how safe that actually is,
but at least


        {-# LANGUAGE Safe #-}
        {-# LANGUAGE Trustworthy #-}
        module Foo where
        
        import Unsafe.Coerce
        
is rejected by 7.6.3. This way, it could work with a single invocation
of --make.


Greetings,
Joachim
