  <!--
  Please provide clear motivation for your patch and explain how it improves
  Bitcoin Core user experience or Bitcoin Core developer experience
  significantly:

  * Any test improvements or new tests that improve coverage are always welcome.
  * All other changes should have accompanying unit tests (see `src/test/`) or
    functional tests (see `test/`). Contributors should note which tests cover
    modified code. If no tests exist for a region of modified code, new tests
    should accompany the change.
  * Bug fixes are most welcome when they come with steps to reproduce or an
    explanation of the potential issue as well as reasoning for the way the bug
    was fixed.
  * Features are welcome, but might be rejected due to design or scope issues.
    If a feature is based on a lot of dependencies, contributors should first
    consider building the system outside of Bitcoin Core, if possible.
  * Refactoring changes are only accepted if they are required for a feature or
    bug fix or otherwise improve developer experience significantly. For example,
    most "code style" refactoring changes require a thorough explanation why they
    are useful, what downsides they have and why they *significantly* improve
    developer experience or avoid serious programming bugs. Note that code style
    is often a subjective matter. Unless they are explicitly mentioned to be
    preferred in the [developer notes](/doc/developer-notes.md), stylistic code
    changes are usually rejected.

  <!--
  Bitcoin Core has a thorough review process and even the most trivial change
  needs to pass a lot of eyes and requires non-zero or even substantial time
  effort to review. There is a huge lack of active reviewers on the project, so
  patches often sit for a long time.
