Nor gritty rest optional rules, etc.Not sure how to vote really, because Random encounters and time pressure aren't house rules.
Anyways, yes, I have seen this. Regularly is subjective, but 'infrequent, but consistently' is one definition I'm guessing.
When doing wilderness travel, we usually have one encounter or less per day (so whether it is a 5-minute workday depends on if we align the recharge workday with the actual days). In dungeons or similarly structured set pieces, we generally stop it with some 'if you go rest, the enemies might discover your previous incursion and plan traps or just run off with the loot' guidelines. Both of these are relatively easy to make work (so it is mostly, as Vaalingrade alludes to, that you then have to include these pressures more than that they don't work or something). It's the messy middle where we see the most problems -- city adventures where there could be more than one potential-resource-draining-situation per rest cycle, but often not and rarely 3 or more.
