Isn't this what different journaling practices try to combat against? To have dedicated time and space to regularly think on what are you doing and why are you doing it. BuJo, for example, places special attention to daily/weekly/monthly reflections.
Because that time you spend using Anki to retain it is time that you could spend seeking deep understandings elsewhere.
In my personal experience, a deep-understanding seeking study session is not portable (hard to take notes when you don't have a surface) and if it's less than an hour long, it's usually not very good (need time to 'warm up' and fully focus). Anki, on the other hand, is perfect for quick study during a break/short commute/being in a queue.
