I do wish people would stop blaming the glycidate and assuming that the only good MDMA has to be made from safrole. Good MDMA is produced from a standard reductive amination of MD-P2P or PMK oil. This latter chemical has no stereoisomers and therefore will always produce, if standard reductive amination techniques are employed, racemic MDMA.
Safrole isn't the only chemical which produces perfectly good MD-P2P. Piperonal can be converted into MD-P2P just as well. And yes, so can PMK-glycidate.
What seems to be happening, if this theory is even correct, is that manufacturers have found a way to convert PMK-glycidate (which does come in different stereoisomers) straight to MDMA, either by bypassing the manufacture of MD-P2P completely or the MD-P2P being generated so briefly before it is then converted into MDMA (kind of like a "one-pot" type synthesis) that one isomer of the MDMA is favoured because the glycidate precursor used was of a particular isomer to begin with.
All the MDMA manufacturers using glycidate need to do is convert it to MD-P2P/PMK first and then extract and purify it for later use; which is precisely what should happen if MDMA is being made properly from safrole as well. The safrole isn't meant to be in the product. It is just via safrole, good quality MD-P2P/PMK (which is the true immediate precursor for MDMA) can be made.
So in summary, the glycidate isn't the problem; but rather it is the lazy and greedy people using the glycidate to make MDMA in the most low cost and expeditious way possible, at great expense to the quality/desirability of the product.
would love to get this printed onto a t-shirt, nice for wandering around a little festival and folk trying to make sense of it while off there heads
