If we take this a little further though,
part of craft production is the curation;
being willing to dump batches that don't meet your quality standard.
Any producer who knowingly ships product below their quality standard is no longer engaded an artisan production.
I think it certainly runs risk of "No true Scotsman". It also assumes that "their quality standard" is higher than that employed in the continuous production cases. I do think it's a good nudge for artisanal producers, which fits your role :-P

Unless this is the 'No true Scotsman' fallacy...
