Ok, I think I understand now. Thank you for the explanations. And that's very interesting.

FYI, up to now, to gather the information about a city, we were doing:
      select ... from planet_osm_line
              where boundary='administrative' and
                    admin_level='8' and

So, as far as I understood, this means that nominatim is able to deliver /at least/ these former results, which is wonderful ! And it will deliver also the "other" results (those with class != "boundary" and/or type != "administrative").

If I understand correctly, we should trust the polygon you return only when class="boundary" ? Or the correct condition should be rather "when class="boundary" and type="administrative" ?

In any case, I think we are very interested in the polygon, even when it's "weird" (eg. class="place"), but we'll probably have to tell this to the user when we present the results (the same way you do it with the icon tag, afaik) ?
