I prepared a lengthy reply that included more information, but never posted it, here's what ended up happening:
We just kind of had to look for glass for a few days... Took the dishwasher apart to look for glass, other than 1 additional shard in the dishwasher, and the one I found on a 'clean' dish that spurred my panic, we didn't find any. Any ultrafine particles of glass ultimately would be comparable to hard water deposits in the machine? I mean, I'm not dead yet, so we're all good here probably.
Glass is probably harder than hard-water deposits. One is a calcium mineral (of some sort, likely carbonate) and the other is silicon dioxide. Regardless, glass isn't going to stick to plates and it's denser than water.
