Its not so much that the designers think that Monks are overturned, as that the designers expect that players will have more encounters and take more short rest per day than many actually do. If a monk gets 3 short rests in a day they are actually pretty powerful.
Monks (and short rest Warlocks) very in power a lot depending on the number of short rests they get in a day. This is incredibly difficult to balance across different gaming tables, because the number of short rests can very widely between different games. I also get the feeling that a lot of groups end up having a similar number of rests most sessions. It seems like most groups tend to either have several short rests a day or none.
The only real solution to this is encourage changing the length of short rests based on your groups playstyle. This is why I have been saying that the rules for changing the length of shorts rests should be in the PHB. The rules should also explicitly explain and give examples on how different rest lengths can effect balance and change the playstyle. Basically the rules should encourage changing the length of short rests so that a party usually has 2 short rests ever long rest.
