The LEW stance has been "If it's in the SRD, it's allowed for the players" for the most part, and those feats did receive quite some amount of discussion. They are allowed, though recently the judges voted to ban two (Persistent Spell and Superior Expertise), and I believe they also voted to remove the sonic option from Energy Substitution. Also, on the off-chance that there will be new additions to the SRD, they'll no longer be considered auto-approved.
I suppose some of that should be in the stickied threads. If it isn't, it's solely the fault of the guy who kicked himself out recently for not updating things regularly.
