If I'm learning a kanji and Jisho lists readings which it doesn't list any definitions for, is it generally safe to ignore those readings on the basis of them probably being too obscure to be useful anytime soon?
For example, 権 has listed readings of おもり、かり、はか、けん、and ごん.
Only けん and ごん seem to be common readings (けん much more so than ごん), with the other readings either having no listed words/definitions/usages, or having more commonly-used kanji for that reading.
