I need to be convinced of this.

Can you sketch an algorithm that will convert SGML-style (or &-less
SGML-style) content models involving #PCDATA into content models
involving #PCDATA and #WS, where #WS is a data type that matches
only white space, such that random white space around tags will be properly
accounted for?

Remember that XML parsers are required to pass along all whitespace,
(i.e. it all appears in the infoset, barring whitespace outside the
root element), so it needs to be accounted for somehow, when it is
#PCDATA and when it isn't.
