The actual minimum speed at which a given aircraft can be controlled is dependent upon the terms you suggest (and others) but that isn't "VMC"
It sure does. Take a normally asperated engine. At 10,000' that engine produces about 2/3 rated thrust. Therefore VMC will be lower at that altitude. Take a heavy aircraft at 10,000'. It is possible that the aircraft will stall before reaching its VMC. Thats the way its always worked.
