Consider merging this module into the more widely known Examples module

Problem/Motivation

I see the followings as reason for the merge:

1. The Examples for Developers → module is probably more widely known
2. That module has a rule to cover Core APIs only but it's fine because SDC now is in Core
3. That module has no SDC-related sub-module yet, not even an open ticket found for that ( link → )
4. This module states that it seeks co-maintainers

Proposed resolution

Copy over its codebase into a proper sub-module of the examples module.

Remaining tasks

Update documentation to notify fellow developers about the change.
