At least the books by Taeubner Verlag do it like this.

I don't want to get into an aestetic discussion, but
simply note that

1. emphasis could be a language dependent feature

2. There may be situations where letterspacing is
required (by some higher power), and TeX/LaTeX is
not well equipped to satisfy such demands.
