We've not used \DoNotIndex at all in the team's LaTeX3 code, so our
indexes show every command. We've not actually discussed this as a
policy, but one can see an argument for indexing everything, as
definition and use will be separate in any case. At least part of an
argument here is that for 'users' you should not need to typeset the
code part, so the index will not show stuff from outside a module anyway.

We've used \tn almost entirely within the implementation part of a .dtx,
with mainly \cs in the documentation part. (We've also use verbatim for
cases where the cs should not be indexed at all.) There, \tn is used for
primitives and things which are clearly 'LaTeX2e-based', such as
\@ifnextchar, rather than 'LaTeX interface' based, such as \textit. (I'd
expect the latter to remain in a stand-alone LaTeX3 format.)
