There is no elegant way to do this with a CLI interface since it is not a static interface, it is a stream of characters. Anything that's not content will have to be inline with user-generated input and output. It would be like a weather app with ads in the middle of the sun icon.
The analogy is just awesome!! Thanks a ton for bringing a smile on a gloomy day :)
Yes, amazon-enabled dash and grep/find/whatever have different functionality. But that's a recent change. Previously, dash had exactly the same functionality. That's the entire point. You add a feature here, you add the same feature there.

You have got to be kidding me. This is a joke.
>Previously, dash had exactly the same functionality
The exact same functionality of which? And I rather doubt that is true.
>You add a feature here, you add the same feature there.
No. No you do not. Not when there is standardized. And in this case the "here"/"there" relationship has not even been established for "ubuntu-dash"/grep, making this extra idiotic.
Uh, yeah?
Off the top of my head you would need to patch glibc, all the major shells, probably half of coreutils, anything that daemonizes similar to nohup (including screen and tmux, god knows how many CPAN modules), ...
This can be observed by running:
bash -c 'times whoami' > /dev/null
