Totally agree this is a lacking feature, thanks for the suggestion!

In order for me to actually get v3 released I have to put blinders on and only implement bug fixes or super trivial features which are simple to forward port to the v3 branch.

I don't know that this is one such issue. I'll leave it open for v3 as it is something I do want to have.

Having said all this, if someone implements this for v2 I'm not against the PR, so long as the understanding is that for v3 I may have to rip out the commit and re-do it depending how deep into the internals it gets to implement this. (for v3 the internals are quite different, so some changes aren't trivial to forward port).

To solve this, we would either need to add a global_help_template function that would forward the template to children (example) or we could add a setting called PropagateTemplate which does the same.
