So, I happened upon this here item while playing (must have been added in either Patch 7 or 8?):
There's clearly framework for "jumping without using a bonus action" in the game, judging by it, albeit implemented in such a wacky manner. I suppose if we were to make jumping / running and jumping work more in accordance with the rules, then these would increase the jump distance / make you able to cover a running jump's distance without expending movement first? Regardless, all of these magical items with wonky effects that encourage you to carry them all on you and hot-swap whenever you need them are a whole different barrel of controversial design choices.
