Is the purpose of this bit to make the callback quiet? I do not
think so. Is there a reason why we cannot call it just OPT_QUIET or
something instead?
When the set of functions that pay attention to these flags include
both ones that are callable for a single submodule and ones meant as
callbacks for for-each interface, having to flip bit whose name
screams "CallBack!" in a caller of a single-short version feels very
wrong.
"make style" tells me to format the above like so:
#define OPT_QUIET (1 << 0)
and I think I agree.

Good.

I take it is a short-hand for "submodule init callback"? As long as
the name stays inside this file, I think we are OK.

Call this just "flags"; call-back ness is plenty clear from the fact
that it lives in a structure meant as a callback interface already.

Blank line here?

Call this also "flags"; a direct caller of this function that wants
to initialize a single submodule without going thru the for-each
callback interface would not be passing "callback flags"--they are
just passing a set of flags.
