There is a popular xkcd post on standards

Why do we end up in these situations ?

One common reason is that we standardize before implementing. Specifications in theory may have limitations that are revealed late in process and natural next step is to have another standard to address it. There are popular terms e.g. "code as standard" which tries to address this situation.

Standardize we must, but do it for existing practices.
