a term used to describe something can only be right or wrong; there is no middle ground for terms.

your reasoning for it not being a right term (or wrong term) is that there's a connotation to dance games with the word 'step'.
while it is true that that is ultimately the origin of the word, there is no longer a strong connotation with the dance game movement. i have been stepping/charting for a while now and i can't remember having ever looked at the word 'step' and pictured feet moving. it's a word when used in keyboard context holds no such connotation for me, and i wonder how much it would for other people. words that mean one thing can have their origins in other word that meant a similar/comparable thing, but not an equivalent one, and over time, that original meaning is totally forgotten. that's the deal with 'step'.

arbitrarily regressing and looking at where the word came from instead of what it currently means as a reason to not use it anymore is a pretty weird thing to do
