Surely it is at least in part. We're talking about the announcement of a new open source project that isn't ready to use yet which would presumably enjoy people helping make it work for them, and a new startup around that open source project that is likely to be hiring in the future (or even maybe right now? Didn't check).

It implies that there was likely a small degree of rigour in the construction... not a large one (very little software has that)... and not a guarantee... but likely more than the abysmally small average in the software world.
