I really don't get what you mean by this ...
I will explain it to you.
Combat is a game mechanic. Games offer combat for a reason. For some games is combat everything, or rather it is their only aspect. In Skyrim is combat not everything. There are many things one can do in Skyrim without a fight, which adds diversity and freedom to the game. The purpose of combat is however a particular one. Combat is there to create challenges.
Power attacks require you to have stamina, just like magic requires you to have magicka. Not having enough stamina should result in a punishment, like not being able to do another power attack and failing to block. It is the same with magic and when you run out of magicka and you become unable to cast another spell. The combat mechanic creates a challenge and the player needs to overcome it by planning for the case when he/she runs out of stamina, magicka and health.
The problem I see is that when it is enough to need only one point in stamina to do a power attack then you lose some of the challenge.
Imagine being able to cast any spell if you had only one point in magicka. Why increase magicka at all on a level up? You could simply use the 100 you get at start and not ever increase the amount of magicka on your character.
Imagine being able to take any amount of damage and to survive if you had only one point in health. Same here. The health regeneration could end up making you immortal.
Ask yourself then, why put any points into stamina when you can just use a weapon like the OP or eat a soup?
Stamina stops being a challenge.
And yes you can play the game the way you like. I think this is pretty obvious. I do like a good fight and the challenge that comes with it. It is what makes a fight good to me. I have no problem with the challenges, in fact I want them and it is why I bought this game.
It kind of creates a new challenge, too. The challenge to compensate for the flaws of Skyrim's combat mechanic and to maintain it to keep combat challenging. This is not why I buy games...
I see it as a bug.
