I'm not sure why you have such a negative attitude towards gov.uk, the site seems refreshingly good at it's job. It's simple, clear and easy to use. As long as they can execute fast what does the tech stack matter?
I think it's fair to say it's going to take a little while to migrate all of the systems over. Give credit where it's due, they're doing a good job with the new site and I'm sure that when it arrives the replacement for the tax disc application will be of a similar standard.
I think the site is good. I have no problem with the technology ultimately but to put a fine point on it, I'm not paying the government lots of money to invent their own infrastructure components when perfectly good ones exist already.
