[Tagging] How to put a name tag on an area with more than one type?

Do you have a suggestion of how to map Sweden's highest mountain,
Kebnekaise?
The mountain is called Kebnekaise, it has two peaks, one is called
"Sydtoppen" ("the south peak"), the other "Nordtoppen" ("the north
peak").
Currently it's mapped with the two peaks where one is called "Kebnekaise
Sydtoppen" and the other "Kebnekaise Nordtoppen". Not really correct,
but perhaps the least bad way to do it? When zooming out, on a regular
map you see the Kebnekaise name big over the mountain, but the names for
Sydtoppen and Nordtoppen is removed. I'd love something like a
possibility to put the peaks in a relation and put the mountain name in
the relation in cases like this.
Kebnekaise is not the only example, it's quite common with Swedish
mountain that the peaks themselves have quite anonymous names like those
on Kebnekaise, "Stortoppen" (the great peak) is another common name of
the highest peak on a Swedish mountain, where the mountain itself has a
different (and unique) name. You don't want to see the anonymous
"Stortoppen"-name when you zoom out the map. OSM-Carto has "solved"
these name prominence issues by removing all names pretty much
immediately, rendering overview maps useless.
One problem with the current peak tag is that the renderer has no
information about the size of the mountain. A peak even if really high
can be a small local peak on top of a large plateau.
(The mountain_range tag is a great tag, but I note that its status is
just "in use", it's not an approved tag :-O.)
