I hear what you are saying and agree it is a bit cloudy using 'trnsaction' and 'feasibility study'. Of course, most feasibility studies are paid for before the study is concluded. I hope he got some $ for it.
Here is what I wrote somewhere else and still feels worthwhile.

The small CSRV engine, best candidate?
In my opinion yes. There are literally 10's of millions made per year covering lawn mowers to outboard engines. No where is the price performance more upside down than the lowly 3hp ICE (infernal combustion engine). There is a sprocket, chain, cam/sprocket and
"then add 2 poppet valves, two seats, 2 guides, 2 springs, 2 keepers, 2 washers and oil/bearing assembly".
With the CSRV you should be able to remove the cost of all the stuff within the quotes " ".
Next thing is the frictional loss of the cam set may be a higher component of lost power in a single cylinder engine. Add to that the idea of replacing motor oil dirtied by the cam/valve area. Both those faults would be gone.
The poppets are placed into an area that exposes a portion of the valve stem to heat warping at high speeds of 2,500 to 3,000 stops per minute. This non symmetric bending of the valve stem causes havoc in the manner of nasty harmonics (a type of imbalance) under reciprocating loads. The CSRV simply rotates on axis, balanced.
The actual head of the cylinder has its passage ways interrupted by the valve and stem, thus making a most difficult casting to mold or injection mold. The CSRV cuts or may even negate such a cluttered passage way, along with the cost to cast, clean, drill, ream and press in seats and guides.
Lastly, longer engine life, lighter weight, lower cost of production, smaller engine required, less fuel needed and more product per shipping container..... it is a no brainer.
When you start to see these little CSRV engines on a same displacement go-cart that dad/mom put together for the 10 year old racer, beat the hell out of the other kids..... It won't be long before NASCAR jumps in.
You are right, it is a paradigm shift. IMO
