I had the great displeasure to work on multiple state-of-the-art algorithms related to sticking things in buckets with varying degrees of optimisation and/or supervision. There are a ton of reasonably recent papers for that, some of them have source code (most of them have nigh-impenetrable theory on why their algorithm is the best) and every case I tested was emphatically much worse than the technologies we've been using for 10+ years in any practical sense. That problem is compounded with the issues you describe, which I'd categorise as probably the best case. I did not find even a single case of a properly opensourced repository that just compiled somewhere that wasn't the researcher's laptop.
