I'm not entirely sure what you mean with "The paper also "recommends" to mention the same in `<tuple>`"

The wording section contains 
```
In [tuple.general](https://eel.is/c++draft/tuple.general) append the following paragraph

<ins>In addition to being available via inclusion of the <tuple> header, ignore ([tuple.syn]) is available when <utility> ([utility]) is included.</ins>
```
This is not a recommendation but a requirement.

Can you explain what your question is? Feel free to do it on Discord if you prefer that.
