So I would just merge the 2 points to one as I saw this done on other places , like for example: https://www.openstreetmap.org/node/1412018239
with:
man_made 	cross
natural  	peak

The problem is the wikipage here -> it si tied with the cross.

So the simplest way is just to remove summit:cross=yes or kee it like it is now, as it is also correct.

And that some maps render like (no offense) sh*t (which maps.cz a.k.a. maps.com are, and it is renderimg multiple other thins like sh*t, e.g. the bridge areas) is none of our concern
