This article has some good points but the reasons we add more logic to templates are:

- just pre-generating everything outside of the template can be very efficients. Especially if you language can't make everything lazy or if you have several representations for the same dataset.

- designers want a bit more freedom that just printing x. Having to go back to the dev team everytime you need a little tweak is terrible

- all templates are not HTML

- it's way easier and faster to prototype

- rendering caching != data caching

- everything is not about display. Linking and injecting resources are a big deal, and putting that outside of the template is a huge pain.

- conditional template inheritance ? includes in loop ?

- stuff like wordpress have entire business based on the fact you can switch templates on the fly without touching the blog code base or without the wp team to know what you are going to need inside the template in advance.

Yes, all of those are reasons. None of those reasons apply if users wwant something understandable, maintainable and secure.

Separation of concerns is a thing that can help designers, no?
