Hmmm, that's always a point of discussion. Even though I completely agree with your general point, I do have a counter argument/question. Isn't the initial degradation of a skill a warning enough? You are only losing 1 point of a stat max. With an average daily gain of 3 and a maximum of 7 stat points, that's almost as close to a warning as it gets without it being just a normal slap on the wrist.
Honestly, I personally don't like the warning signs hanging over my head all the time, so that's why I opted not to have anything like that here. Almost constantly forcing me to split attention. The penalty is minuscule if you just forgot about the stat and was planning to keep it up. I would completely agree with you if the degradation was something like 10% or even 5% of your current stats, but you are never losing more than 2% of you stats (usually closer to 1%), and you can replenish that almost instantly if you are ever planning to.
