If it is considered a problem, then yes.
As long as the game has per-day use of powers (whether they're explicitly 'dailies', or x/day as in 3.x barbarian rage), and per-day healing, then there will always be a strong temptation for players to go nova and then rest. And there's only so much the DM can do to stop this behaviour - not every adventure should be on a ticking clock, and throwing nightly ambushes at the PCs can just make the problem worse.
So, yes, if the fifteen-minute workday is a problem, then the rules have to go some way to addressing it. Getting rid of those daily resources is probably a good thing.
(That said, in many cases it is adventure design rather than rules design that causes the problem - encounters on the edge of what is possible will always prompt a fight/recover cycle.)
