Thanks!  I rewrote this to follow our more formal change log 
standards:

    gnu: python-mpv: Update to 1.0.7.
    
    This fixes the build after the core-updates merge.
    
    * gnu/packages/python-xyz.scm (python-mpv): Update to 1.0.7.
    [source]: Remove snippet obsoleted by PY_MPV_SKIP_TESTS.
    [build-system]: Switch to pyproject.
    [arguments]: Set newly-available PY_MPV_SKIP_TESTS variable.
    [native-inputs]: Add python-pytest and 
    python-pyvirtualdisplay.

Origin [modules] are only ever used for snippets, so with the 
snippet gone this served no purpose.  Removed.

After our chat on IRC, I reverted this dubious ‘guix style’ 
indentation change.  This makes your diff a breeze to read and 
shortens some lines that had grown over 80 characters.

As things stand, I don't recommend running ‘guix style’ on 
existing code.  Maybe one day.

I added the newlines that we both preferred.

Line comments (;;) are full sentences, so

  ;; Needed for tests.

Pushed, minus some other ‘guix style’ noise, as 
a977900d76b7585c401222a3ce8bbb82e5f6da45.

Kind regards,
