It seems that the pin receptacles for the battery/external connection are now pre-installed on new KX2 transceivers, even if ordered without the KXIBC2 option. That’s good news for (new) KX2 owners, as it means a KXUSBC2 installation is possible without soldering 
I’m not sure what to think of the soldering job done at the Elecraft factory though (photo of a brand new KX2 unboxed today)…
