Although I expect some improvements to be possible, I doubt it's practical to do the sort of large-scale transformation that would really make a difference.

I mean, I keep reading stories about how famous corporations have terrible codebases which they can't fully fix it, and we're in a domain where deployment is trivial amd doesn't literally cost the time of the entire legal profession to familiaise themselves with the changes.

I'd love to be wrong. The saying "ignorance of the law is not an excuse" is necessary, yet at the same time not possible when the law is as complex as it is now.
