The routine I provided only opens E: if iocb #0 isn't already open.
Therefore it shouldn't destroy any existing redirection.

If this is the case I think the function should be added to the runtime
lib.

But it must not be called automatically from crt0.s, since for non-text
programs E: shouldn't be initialized. The user has to request it
explicitly in his program.
