Render individual Via Ferrata sections (with difficulty)?

[MarijnS95]

I just stumbled upon this website which renders an icon, the name and grade (in Schall scale) of individual Via Ferrata segments on the map:

Looking at the "OpenStreetMap" way this information is already available in OSM as via_ferrata_scale (2 = B), and according to https://www.osmand.net/docs/user/map-legend/osmand#via-ferrata this should also render as a specific path style, yet this section on the OsmAnd map renders as Hiking from Path difficulty. Furthermore, Details doesn't seem to show the value of the difficulty tag:

Only when I turn on the "Hiking difficulty classification" does it use sac_scale=demanding_alpine_hiking to show a purple dashed line (again from Path difficulty):

A bit further on this road the actual Höllental Klettersteig is rendered as a Scale 3 Via Ferrata (and after some fiddling with POI overlay, I even have a clickable point - but there are two Via Ferrata items in the POI overlay list now):

The only difference I see is the linked section has highway=path here whereas the Höllental Klettersteig is highway=via_verrata, and only after writing this issue do I think that it's related to #12823. There used to be a rule (removed in osmandapp/OsmAnd-resources@1e7d033) that seems to translate any highway=* to highway=via_ferrata if it has the via_ferrata_scale attribute?

Is there a way to get that behviour back, or is the correct fix to start marking all these ways (even the short Brett section I linked at the start) as highway=via_ferrata? That seems to be done in the history of e.g. https://www.openstreetmap.org/changeset/140904963 for https://community.openstreetmap.org/t/mappen-und-rendern-von-klettersteigen/69524/2, but https://wiki.openstreetmap.org/wiki/Proposal:Via_ferrata#Criteria_for_taging_as_either_via_ferrata_or_path describes that this may depend on the difficulty. Either way, I'd love to see this information in OsmAnd :)

EDIT: the route for this way https://www.openstreetmap.org/relation/3201006 unfortunately isn't annotated with its via_verrata_scale either and route=hiking (like for Stopselzieher around the corner) but i.e. https://www.xctrails.org/map/map.html?type=allferrata is rendering it all either way.

Back to the original title:

1. Is there a way to render the scale next to name, or below the icon (as in the screenshot from outdooractive)?
2. Is there a way to convert the numeric scale to e.g. Schall scale (or others)?
   EDIT: Looks like it may be difficult to reconstruct i.e. A/B difficulty unless osmandapp/OsmAnd-resources@53d16ba is changed.
