Let’s throw the baby out with the bath water. Highly specific types are very useful on screen-limited mobile devices as they allow software developers to implement very specific controls for them. It ticks me off that now I have to lose my 10-digit input keyboard for these fields and have to use the tiny on-screen keyboard for everything. Reading the article and the linked UK.gov article, it seems like there are two issues: (1) lack of more specific types leading software developers to (2) make bad decisions related to the number type for things that are numeric but not countable numbers. How about we just add a few specific types, or a subtype mechanism. Eg specific types for dates, PINs, and so forth. We would also need to add either a non-countable number type or a subtype of the existing number type. Under the hood it could even just be implemented as a string limited to digit characters, and would be usable for zip codes, etc.
