I believe your recalling incorrectly. Amaury Sachet specifically referred to this issue needing to be resolved as priority in his recent interview with CoinSpice a week or two ago.
After three or four attempts at propogating a block, most miners will ignore that pools blocks and keep mining the previous one until they verify the garbage block. Orphan rate moons.
“Orphan rate moons” You don’t see this as being a priority issue that should be resolved before increasing the blocksize well beyond what is needed right now?
