It doesn't make sense to have tags for different font faces because there are infinitely many. At the same time we do not have a palatino tag even though this is one of the most popular non-standard fonts for LaTeX documents (used, e.g., in
classicthesis and the
memoir docs). Usually font questions revolve around how to use them in LaTeX which is font independent in the case of OpenType fonts and package dependent for Type1 fonts for which there are package tags (e.g. times, eulervm, etc.).
However, I do not want to generalize the statement about font tags to computer-modern and latin-modern. These still deserve special treatment as they are the standard fonts which most users are confronted with on a daily basis. Therefore I consider them to belong to the circle of TeX and friends.
