Is using VPP as a Home Gateway possible at this time in 1.4 rolling? If not, is there a timeline to support it?
VPP support is still extremely experimental and undergoing development.

Side note i believe nat is still experimental within the VPP code base which could be difficult for 99.99% of home use cases.
Here is the current status for VPP support in 1.4-rolling releases:
