Over the years, I have scaled down my work on scales. Having had a teacher for more than two years who never asked about scales contributed. Sometimes, when I want a break from my pieces, I play a couple of scales. Never scales with more than three accidentals, and minor scales only harmonic. Never contrary scales, only parallel ones.
Once upon a time it was good for me to learn these scales, but I really don't see the point to rehearse them over and over again. And I also don't see the point of torturing myself with scales in keys that I don't even play.
However, if a piece is in a key with more than three accidentals, I do check that scale, and play I IV I V I, and I IV I V7 I, just to get a feeling for the sound.
