It doesn't. Just go to any cyclocross race and ask people, whether running pressfit or threaded you have to do regular maintenance on BB and hub bearings whether threaded pressfit or straight pressfit or cup and cone. Generally in those cases the bearings fail not from the loctite retaining compound failing on the outside of the bearing but rather water getting past the seals. I actually prefer my BB30 cyclocross bike because bearings cost $2-3 each and I need to swap 3-4x per race season. They don't creak when I press them out, they just get a bit gritty, and I can do a swap in ~30 mins.
