Actually yes, lua would be a good forced default, since rpm contains an
internal lua interpreter and would need no external deps to process the
script.  Of course, regardless of what /language/ the script is written
in, the script could call upon things that are both "core os" utilities,
as well as "applications".  We have to account for both in the ordering,
so why not just account for both, instead of trying to draw some fuzzy
line in the sand?

Very very few things require special handling, rpm handles that for us.
And yeah, you can assume that those things will be installed, but not in
what order, which is why you have to give the system that installs the
software ordering hints.

Or you could have done it right in the first place and we wouldn't be
filing a bug against your package.
