IRS Form 1040-EZ was eliminated years ago, but even when it was in existence it was never suitable for the majority of filers. (There is now a more limited "simple" form 1040-SR for "seniors"). Nonetheless this seems to have helped feed the myth that having the IRS auto-prepare a return is simple and will work for many if not most filers -- it turns out that lots of info required by the tax law is not already available to the IRS each year.
Anyway, with tax preparation software and electronic filing, the concept of "tax return pages" isn't very relevant any more.
The US has the 1040ez which is the same idea, it's all that's needed for the majority of filers.
