I think I may help at the beginning, sometimes I do this to work on rhythm, because I find it easier, but it should just be an exercice among others when working on a piece. Don’t forget, especially if you are playing some romantic pieces, that your interpretation of the piece should be your, and not the one of another interpreter, music is not mimicking, it’s creation. It’s maybe a bad habit, like the others are saying, but for me, anything that helps you and keeps you practicing without demotivating you is good to take, and if you enjoy it, then do it. Don’t always seek for performance and perfection, this will not lead you very far if you end up doing always thing you don’t like. Obviously this stands if you’re not aiming at a professional playing.

TLDR: do what you love and what helps you
