It is not unexpected behavior.  \RemoveEmptyStaves can only work after
the line breaks are known and the line breaks are the result of
horizontal spacing.

Basically you'd need to redo all of the horizontal spacing after stuff
like \RemoveEmptyStaves have run without changing the line breaking
again if you find out that this gives you more space to work with.

Unlikely to happen in the next few years of LilyPond development.

Okay, thanks for explaining. For now I am content with using “\omit Staff.KeySignature” and “\revert Staff.KeySignature.stencil” respectively to get rid of the problem.

What I found strange, though, was that in my score the problem only appeared when there was a time signature change at the beginning of the line. I couldn’t reproduce this in a minimal example.
