I agree, that's the name I proposed when I asked for the feature...

Well, for la-x-liturgic it would be 5, but we built the patterns so that 
this value is not needed. It could still be there though. What I mean is 
that words of length 5 or more should be hyphenated, but if I understand 
the LuaTeX manual correctly, that means a hyphenationmin value of 4...

Thank you,
