Most of the software I've built doesn't have "a spec.", but let me zoom in on specs. around streaming media. MPEG DASH, CMAF or even the base media file format (ISO/IEC 14496-12) at times can be pretty vague. In practice, this frequently turns up in actual interoperability issues where it's pretty difficult to point out which of two products is according to spec and which one has a bug.

So yes, I totally agree with GP and would actually go further: a phrase like "we found all the bugs in the database" is nonsense and makes the article less credible.
