So XC is "experimental"? Like the planes?
No. They still sell XC parts. It means that it is still in the qualification period and you should use it for non critical applications. As has already been said XC will work fine

XC runs hotter than MC.
That is not a valid rule. It may or may not be true for the 68882. (Is it true?)
The 68040 and 68060 both run hotter in XC variants but not because of the XC/MC status but because they changed technologies between XC and MC. A lower level geometry often means less heat.
