It's sort of funny when the pro list includes "better for science" and there's still a need for a con list. There should be a scientific equivalent to the hypocratic oath; a lot of us laypeople imagine that scientist default to "good for science" and "ease and possibility of replicatability."

Yup.

CS scientific journals should make the bar much higher in that regard: no code? no publish. unless really good excuse.

I mean this is just unrealistic. There are plenty of valid reasons not to want to publish code. For example, you want to commercialize the product. As long as you are given a description of the system you can always go and reimplement it yourself if you are not being lazy.
