BTW: The fact that TYPO3 just stores the number of relations in a field that
is using MM tables for relations to other records was the reason why we
thought about the concept of "virtual fields" for the tagpack at all.

Usually this information is not necessary to get the related records when
displaying them in BE or FE output. So the question was: Should we pollute
"taggable" tables with additional fields when these fields are containing
pretty useless information only?

One advantage of the "virtual fields" is that you don't have to remove them
from each and every table if you don't want to use the tagpack anymore.
Another one is that we use more SQL queries and less PHP arrays to get the
necessary information, which is better performancewise.
