Different use case - for annotations, the *reader* of the code is one
of the intended audiences, so as the author of the code, you decide
what you want to tell them, and that then constrains the tools you can
use (or vice-versa - you pick the kinds of tools you want to use, and
that constrains what you can tell your readers).

This case is different - there are no human readers involved, only
automated tools, so adding a mandatory redirection through a sequence
is just a small performance hit rather than a readability problem.

Cheers,
Nick.
