That article you linked can easily be used by secular Buddhists to justify their position.
Let’s try to do it halfway, we already have rebirth evidences, by verification of kids recalling past lives. However, there’s no easily available evidences akin to rebirth evidences for say spontaneously reborn beings or kamma across lifetimes or supernormal powers.
So if we take this halfway standpoint of admitting rebirth and literal, but devas are myths, stories, not factual. Then it still also breaks Buddhism apart.
For when there’s rebirth, there’s no beginning to it which is seen.
Thus, before humans evolved on earth, we must have been reborn in some beings. Maybe animals, go back to before life evolved on earth then. Maybe we were in other planets. Go back to before the sun and planets were formed. Which realm were we in back then?
We are forced to posit spontaneously reborn beings, that is gods, asuras, hell or ghost beings. And only certain Brahma gods survives the contraction of the universe, to live on to the next cycle.
In many suttas, the Buddha also mentioned directly he has many supernormal powers, able to use divine eye to see unbelievable things. And in some of them, the statement was so short that it doesn’t seem to leave much room for mythological readings of the sutta.
Anyway, with the existence of gods, comes the notion of supernormal powers, which then can be used to see kamma as pattern of many people’s rebirth.
So although indeed, people tend to be more literal reading now and we can enjoy some mythological readings sometimes, Buddhism still does require the literal reading of rebirth, kamma, supernormal powers, spontaneously reborn beings. As defined in right view.
