Well. It looks natural for me. Depends on what you are used to when
working with org babel.

Things are a bit more tricky for latex source blocks, but you can still
do

#+name: nw
#+BEGIN_SRC latex :tangle no
\usepackage{…}
\usepackage{…}
#+END_SRC

#+BEGIN_SRC emacs-lisp :noweb yes :tangle yes :noweb-prefix no
(setq latex-header <<doc-escape(str=nw)>>)
#+END_SRC

Of course, it would only work for source blocks with corresponding
ob-*.el library. But then again, why would you need to wrap things into
text source block when a simple paragraph is enough.

Best,
Ihor

Applied.
