Less severe, but still significant, as in practice, many fonts may be
included (e.g., because of the different levels of heading, I assume).
For instance, on a typical computer-science article:

On this article, the conversion from CM (using aeguill) to LM leads
to a 80% size increase (more than 200 KB). So, this is still quite
bad in real world (both concerning network transmissions, which are
not always very fast, and concerning data storage on mobile devices,
where space is rather limited).
