I don't think it's a joke.
Only risk is if he gets injured badly or perpetually like Lynch.
End of '32 takes him basically to the end of his playing like at age 33 more or less. We have seen enough of his skillset to know he's a gun KPD when he's on, but can also go forward or ruck part time.
Still should be unleashed in the midfield or wing IMO.
If all of Gibcus, Young, Miller, Blight, Broad etc are fit I would consider Balta straight up playing midfield for pace and aggression.
