You are missing the point.

How many actually try to reproduce the results by writing corresponding code themselves? Apparently lot of papers with slightly wrong findings because code errors have passed the peer review (all of us in the SWE bubble know how often bugs occur), at least in less prestigious journals.

There is nothing wrong with mandating the code to be supplied with the paper. Because, many time code is somewhere between the experimental setup and proof / result.
