My personal preference is for all successful environmental challenges to provide XP... however, 5e did away with the 4e's 'non combat encounters' rules and left just some vague info. It's up to the DM if they want to give xp for this sort of thing or just add it up at the end of an encounter.
Seeing as you need a successful perception check to even find the traps and then a successful disarm on the first try for it to not blow up in your face, I'd like if it awarded xp (not just the satisfaction of not getting blown up).
Atm, murderhobo playstyles still award more XP than diplomatic ones, and deceptive playstyles more than murderhobo ones (disguise, do a certain faction's quests for items+XP, start killing ppl off in stealth/invis/bribing for items+XP, double profit).
