Ive downloaded over 150k tracks from tidal using tidal dl and after a lot of testing the most theyve done to counter is rate limiting or blocking the IP i was using, but if you stick with reasonable limits of how quickly you are downloading tidal doesnt seem to care much.

I've been using both extensions almost every day for more than a year without getting banned, but there is always a risk.
Since the code is running inside a real browser, it might be more stealth than command line tools, not really sure about that.
Original tidal-dl-ng had a delay option to wait between tracks downloads, maybe i'll implement the same feature.
