it's more like bonuses to current gameplay
the wings really help with mobility and the beacons are very nice for projects/around the base
there isn't really too much specific "end game" content in minecraft, it's a sand box game, so the end game content is what you want it to be
for me I like building technical things, so that's what I spend my time on
people who want to fight things will be disappointed though, mostly because minecraft combat is terrible - instead a game like borderlands/terraria would be better
