I think the issue was vertical alignment of elements on different lines,
using different faces.   E.g. a first (header) line in one face,
followed by various lines in some other face.

OTOH, you can usually add a `default' face to the TABs to impose the use
of a uniform tab size, so maybe it's not a real problem.
Maybe Gerd remembers?
