No one, except for some very stupid people, can think that if they have an option, they should use it.
I, personally, stop pickpocketing by the time I crown, mostly, and this is about level 15, just before piramid.
I, and only I, prefer just waiting to use of First Aid, except for vital situations. Does it mean it should be removed and replaced with an increased regen? (btw, this can be an actual factor of success, I'm sure trained First Aid could have saved me a lot of times)
I, and only I, almost never use missles. Does it mean missles should be removed and replaced with better melee attacks? (this also can be a factor of success. The rare times I care to pick up a pile of stones to kill a carmic lizard ensure me it is)
I, and only I, almost never smith. Does it?..
I, and only I, used music only when playing bard.
I, and only I, only visit DF on level about 20.
I, and only I, almost never pool-sip.
I, and only I, do NOT use starvation to raise stats.
Does this all mean that features listed should be removed? I think it doesn't. The removal would not hurt me. But it would hurt other people.
And so would your suggestion.
