5E is designed around the assumption that players do 6-8 encounters of various sizes per day with about 2 short rests in between each long rest. I believe this is stated in the DMG.
The number of spell slots a warlock gets is based on this assumption.
However, it seems that the short rest button is only usable once per long rest. I can see this being an issue for warlocks since it cuts down the number of spell slots they can use per day by a lot.
Right now it doesn't really matter since we can long rest whenever we want with no consequences. But I see that getting fixed in the future. Depending on HOW that gets fixed, it could really affect the balance of the warlock in relation to the other classes. Monks, too.
I personally tried to avoid using long rests in my playthrough unless I absolutely needed it and I found that Wyll's spell slots were pretty limited, even more than I would expect for a warlock. Especially since Hex is basically a spell slot tax.
