I would put it in a +start my workday+ routine. It was suggested earlier in the journey. It is based on principle that environment triggers habbits. Some habbits may be more suitable for work environments.
You asked “Do you also find it weird that it’s right at the end of the morning routine? Where would you move it to?” What do you mean by “it” ? In my opinion you can reorder habits to make sure that you keep them. If you mean the deep work habit, I have breakfast after it; so that I can take a good break after hard work. Ask again more specifically so I can help you better.
