that's mainly what I've heard. About the plastic still being porous to allow oxygen in. at my local brewing supply store they've said told me it's fine for a few weeks but any longer and they would recommend glass.
I think the longest I've done is 4 weeks (2 in primary and then 2 in a secondary) and they came out fine....
