Yes definitely....pure lifting body without wings is pretty much obsolete in homebuilding for sure.Effective for what?
It is absolutely dubious because (in my opinion) the true lifting body is the very least efficient aerodynamic configuration of any flying machine. The government and the military can afford to use this configuration if it were necessary, but commercial aviation and certainly private aviation cannot afford this. The lifting body was invented and tested as a way to return astronauts to the ground in an environment where wings are too easy to damage or break or burn up. But the lifting body is so inefficient that it was worth the effort to put wings on the Space Shuttle, despite having to solve the heat and structure problems.
All homebuilders are operating their aircraft where re-entry from space is not an issue (sorry Burt... almost all homebuilders). So the one and only real aerodynamic advantage of a lifting body is not present.
What we're left with that is relevant is the cost of fuel, the amount of power needed for level flight, the distance for takeoff and landing, and the amount of training necessary for the target pilot population to be competent. None of these factors favors or even tolerates the true lifting body.
The blended wing/body configuration is different, and is potntially relevant to homebuilders as Barnaby Wainfan's Facetmobile has demonstrated. But tis is nowhere near a "lifting body" like the HL-10 and M2-F2 NASA programs.
The Facetmobile proved to be far more efficient than anticipated, and there are very important advantages that this type of configuration could possibly deliver to general aviation.
