Would filters or transformers be enough?  If output of the
compiler generated stream writer (perhaps respecting 'Output
of components) is formatted preditably, the output can be input
to a log inspection tool. The tool then produces the final output
formatted as desired without an effect on the original program.

(Maybe the transormation can be done running the circuits
of Ada.Tags.Generic_Dispatching_Constructor.
Resorting to a dummy tracing tag when there isn't a tag
for the type to be output.)
