They can be converted.
Calibre will not add KFX files directly from the device for some reason ('KFX is a virtual format' blah blah), but copy them to some other location, and it will add and convert them.
As to why Amazon has not enabled this for older firmware, we can only speculate.
It seems to me this change could have been made at any time after Send To Kindle service was capable of converting ePub to KFX (i.e. with launch of Scribe), but they waited almost 10 months to do it.
I assume KFX downloads are generated on demand, so to the extent that the conversion from ePub has improved over that time, delaying means they have spared users exposure to the issues that have been fixed. And perhaps now they'll move on to the next group of Kindles, which naturally would be a lower priority.
