It depends.  All programs running in the same AG should be designed to share
the same resources.  Conversely, if you pick an AG for a program, it should
be designed to share resources with all other programs in that AG.

So.  I would ordinarily advise against running ILE programs in the DAG
because you can't reclaim their (shared) resources.  Remember that ILE
programs (running in a named or *NEW activation group) inherit OPM issued
overrides.

So they're all running in the DAG?  Well, you won't get the common
activation mistake because you can't reclaim the DAG!  Aside from that, I
can't think what trouble you might run into, but I don't personally ever run
ILE programs in the default AG, so my experiences in this regard are limited
to tinkering and testing other folks' scenarios.
