All Christians and Jews consider Ezra and Nehemiah to be canonical. Jews, Roman Catholics, and Protestants do not generally recognize 1 Esdras and 2 Esdras as being canonical. Eastern Orthodox generally consider 1 Esdras to be canonical, but not 2 Esdras. The Jewish Apocalypse of Ezra is part of the Syriac and Ethiopian traditions and in the Apocrypha of the Armenian Church.

This would make sense. According to the bible the original purpose was for the Jews to accept the messiah. But they didn't. It makes sense this could be a vision of the end of that era where the Jews accepted Christ. But as it became more apparent they would not, and then they didn't, the means by which the purpose was to be realized changed.
So I have trouble seeing what this proves, even if it resembles revelation. If it was an older writing than revelation from a source other than Jewish or Christian in nature then there would be room to make an argument.
