I feel like everywhere we use ptr.To instead of Go 1.26 new. Should we really change that? We also use ptr.Deref in some cases

Personally new is also kinda confusing to me, new what? 🤷

Is that new recommendation coming from the golangci-lint modernize plugin?

Everything changed were just recommendations by modernize and even though new reads a little weird in these use cases, it does what it used to do in other languages as well. It creates a new 'object' and returns the pointer to it.
In general in would not argue about that. It is a language feature that deprecates other libraries so we should use it.
Also the ptr.Deref is something we should still keep because we do not use it for dereferencing but rather as a defaulting function. Otherwise we could have just used & :D
