Could you explain why you feel the existing support functions are
insufficient?
Because it is not possible to outsource the scan of pg_wal/summaries/
to a different role, no?
I was under the impression that you could do this with
pg_available_wal_summaries() [0].

https://www.postgresql.org/docs/current/functions-info.html#FUNCTIONS-INFO-WAL-SUMMARY
One benefit of supporting something like pg_ls_summariesdir() is that
it allows us to view the last modification time of each WAL summary file
and estimate when they'll be removed based on wal_summary_keep_time.
Of course, we could also extend the existing function to report
the last modification time if this use case is valid, though.
