OK, so with the discussed changes, we get this:

3.7 wil become 1.7 and apply convention-wide: Reference fields are
prefilled with the reference designator of the part (IEEE 315-1975).

6.10. Text is placed on silkscreen and uses a height of 1mm.
6.11. Doc property contains a full description of footprint.
6.12. Keywords are separated by spaces.
6.13. Value is filled with footprint name.
6.14. Attributes is set to the appropriate value, see tooltip for more
information.
6.15. All other properties are left to default values. (Move and Place:
Free; Auto Place: 0 and 0,  Local Clearance Values: 0)
6.16. 3D Shape ".wrl" files are named the same as their footprint and are
placed in a folder named the same as the footprint library replacing the
".pretty" with ".3dshapes".

I will amend the convention shortly.
