That’s a good point. If you need specific visual alignment with an arbitrary number of characters on the previous line, then spaces are appropriate. Tabs should be used for the initial semantic indentation then spaces for additional visual indentation beyond that. (Whether visual alignment of this sort is desirable is a different question. If you want it then spaces are appropriate.)
