It's probably unusual now because bike mech. first suggest you to change the wheel when replacing a cone that cost about 10$ in part.

That's the first thing I was told... They make a bigger sale that way too.
It's certainly true that if some one changes the cones for you, it is not worth spending 30-40$ including labor time for an old wheel. But when you do it yourself it takes 10-20 minutes max.

I just learned that I should grease my wheels multiple times per years (every 200 miles)... My commuting cones are completely shot. One bearing exploded in the wheel! I couldn't believe how stupid I was to treat my bike like this. I always put oil on the chain and important & accessible components if I knew that earlier I would have probably saved my cone. I am pretty sure a minority of biker know that they should do that...

When greasing your bike costs 150$CA to do in a LBS I believe some prefer not caring and just ride it till it die.
