The potion he was given certainly does extend his sleep cycle, but if they can extend sleep cycles with potions, then it seems likely that they can shorten them with potions.
That sounds reasonable. I’d take it as evidence that someone (probably Dumbledore) had a hand in opting for the Time-Turner approach: if we can infer that there are two plausible options and the more expensive and potentially disruptive one was chosen, there’s most likely a reason for it. And we already know of one character who has an interest in enabling potential heroes by way of mysterious gifts.
Doesn’t explain why Dumbledore and co. decided to lock down the Time-Turner when it ended up being a little too disruptive, but there are a few options there. Perhaps they didn’t want to set Harry against them by too obviously withdrawing favors, or perhaps Dumbledore intended the obstacle to be overcome (as per the third floor corridor).
