Sure there is:
  (ada-xref-get-project-field 'main)
does what you want I think

Try: ada-xref-set-default-prj-values, which initializes a project if
there is none yet.

Not quite in fact, since we have added several features in the ALI files
(like better support for generics) that are not used from ada-mode. Also
GPS has caches all around, which makes queries like find all occurrences
of an entity much faster there.

Since this was GPL, I could find that version. But to compile it you
need access to the GNAT sources, and it isn't really easy to distribute
as a result.
