Thanks for this contribution as well, @monsieurp!
Hmm, quite a few core modules depend on Rex::Template so I'm afraid we can't simply deprecate it like that. I'd say we have to make sure the internal template-processing keeps working as before (and without deprecation warnings if not used directly).
We might need to move the discussion and design part back to the original #1475 issue. As briefly mentioned there, my preferred way would be to see if we could migrate the internal custom logic of Rex::Template to something like Text::Template::Simple (which seems close enough syntax-wise), and then perhaps making Rex::Template::NG to be an alias of Rex::Template (with a deprecation notice upon import).
What do you think about that?

Is there any reason why Data::Dumper is also removed in this context about Rex::Template::* deprecation?

We have Rex::deprecated to mark things deprecated in Rex core in a uniform way. That might come in handy here too. Or perhaps during import time of Rex::Template and Rex::Template::NG.

What do you think about pointing to Rex::Template::TT as a readily available and recommended external module, and point to the docs about how to set one's own custom templating functions:
- set_template_function config option
- template_function command
Fixes #1475.
This PR is an attempt to fix #1475.
