It may or may not have anything to do with the truth of the teaching; it may have a great deal to do with the wisdom of it and whether or not it is truly dogma.

But if something is true, then it is wise to promulgate it. At least as far as God's laws are concerned. To act against the true, even unknowingly, is to act against your own nature.

[Kolokotronis]

"But if something is true, then it is wise to promulgate it."

To teach it, yes. To make it a necessary pre-condition for theosis/salvation, no. Something like ABC simply doesn't rise to that level.
