I am OK with that. Perhaps a special recommandation should be issued to
take care of large polygons where the warp can be seen "with naked eyes"
from the side.

Special care should be taken with parts that exist in transparent
versions as overlaps cause visual artifacts.

Agree. Leading 0 enhance human readability.
