But why do I have to do it? I would only like that
\switchtobodyfont[20pt] scales the font properly (according to
whatever definitions are default). I can't define that for all the
possible sizes of the font that I want to use in the document.

\switchtobodyfont[iwona-t5,20pt] works OK, but one command after
another doesn't.
