Subject: Mesh Deform Modifier: compress static binding weights better,
 threshold is still set very low so in many cases it could be even smaller,
 but being a bit conservative here to try to avoid breaking rigs.

This is not forward-compatible, i.e. loading new files in older blender
versions will loose the binding.
