yes.

Indeed. Use increment/dt?

avoidRatchetting does apply for sphere-sphere only, as mentionned in 
comments. So, it is consistent to hardcode "false" for sphere-facet.
Let you commit.

Yes, I know what you mean... Here however, you have to re-learn because 
you want to use a new feature (periodicity). :)
With recent changes, it is theoreticaly easier to write a law, but yes, 
it is always annoying when you have to re-learn something you used to know.
