I agree, and if anything the problem is even worse. You mentioned characters with 6 readings, here's one with more than 30:
https://en.wiktionary.org/wiki/%E7%94%9F
And while you can usually figure out which reading applies based on what follows, there are still many cases where you can't. A standalone 今日 can be any of "konnichi", "kyou" or "konjitsu" depending on context and intent.
To be clear, that list contains about 12 non-name readings, of which about 7 are productive.
that's six more than can be displayed at once, and without looking at the entire sentence context it's not possible to choose the correct one.
