Seems simpler to set you soft cap, and have players track what they spend their over the cap xp on.

If skills fading, or becoming outdated is a thing, just assign a penalty to the skill and some sort of task (say learning rolls) to re-update.

XP are not a learning simulator. So assess how they behave based on what you want players to experience, and do about it, and what you want your world to do.
