In short, it acts as a net-negative to both the Stormy weather (and any WeatherTweaks combined weather that includes it) and CodeRebirth in general. Whilst it is cool aesthetically and for "immersion" and such, for gameplay it just makes Stormy worse since you miss out on Crates/Safes, and it makes CR worse because you miss out on one of it's most enjoyable pieces of content if the vanilla weather is ever present.
At the very least, decreasing the chance of it happening, or making the effect only happen after a certain point in the day rather than instantly would make it much more bearable.
