Think about it a little. The rear derailleur guides the chain from the middle so it doesn't care.
The front derailleur guides the chain from the sides. 9-speed front derailleurs are a tiny bit narrower than 8-speed. I'm told the difference isn't a problem for double chainring conversions but I've found it necessary to use a 9-speed front derailleur when converting a triple.
