“...a messianic figure who ascends to heaven and receives divine revelations was seen as problematic. This portrayal could be seen as conflicting with the unique status of Jesus Christ in Christian theology. The early church was cautious about texts that might elevate other figures to a similar or competing status”.

I'm not sure how far to take this, but when I read that I immediately thought of Paul. He claims to have ascended to paradise, or the third heaven depending on the translation, and had divine revelations, great secrets. The Church was not reluctant to include his texts as part of the canon. They actually form the majority of the New Testament.
