It's a balance I think. I gather (after going back to read arguments and discussions during my free time) that Testing wasn't even a thing, till people relentlessly pushed vendors to raise standards and start doing it.
Even as at April, it was common to run into a greymarket/UGL vendor bringing only a COA for their raws. Word spread fast and now new comers pop up with hot off the lab-floor Jano tests (or whatever lab they can afford)
Same goes for the push to have better crimps, bungs, filtering for oils for floaters, e.t.c Some have even pushed for vials to have the proper 10mls and not 9.2 or whatever the underfill is.
It is therefore inevitable that folks will keep pushing for other things and vendor competition may eventually make such things become the norm.
