Morten Thaysen, a clean air campaigner for Greenpeace UK, said: “The government is saying all the right things about the huge cost in human lives and money, but is proposing nothing new to tackle pollution from road transport. A 2040 phase-out date for diesel and petrol is effectively saying that yes, your grandchildren deserve clean air, but your children will have to go on breathing toxic fumes so as not to disrupt the car industry’s sales forecasts.”

A spokeswoman for the Department for Environment, Food and Rural Affairs told the Guardian: “We will not weaken our environmental protection when we leave the EU, but will maintain and even enhance our already high environmental standards. Our clean air strategy shows how we will go further and faster than the EU in reducing human exposure to particulate-matter pollution. This will be underpinned by new England-wide powers to control major sources of air pollution, plus new local powers to take action in areas with an air pollution problem.” Some time ago I wrote a post on form generation.

A form generation library is a hard library to write. You have to balance complexity and features. There are a lot of potential features. How do you tweak the forms? How do you control layout? How do you handle repeating form elements? How do you handle elements that require Javascript? Server-side resources like CSS and Javascript? Server-side communication like auto-complete? A simple library cannot handle a lot of these. But very simple forms don't need form generation libraries. So a simple library only handles a narrow band of use cases. A complex library can potentially handle all these cases, but can be difficult to use for the most common cases.

I will assert that as the libraries are usually designed, there is no good balance. Not all problems have feasible solutions. Form generation libraries are one such problem, but they don't seem to be such a problem.
