No idea whatsoever. To be honest, I don't even know why we have so many 
service names just for the formula parser. Because internally there is 
only one parser implementation. So, whichever service will survive, we 
need to have at least one of them left standing.  That's what I meant.

We would probably need to ask Eike for anything more specific than that.

Yes. com.sun.star.sheet.FormulaParser is the one I'm familiar with. The 
rest were totally unknown to me.
