I don't think those inferences are justified by the passages you quoted. Listing words together in a list of possible responses is not the same as saying that one includes the meaning of another. Upon hearing the word "roger," a controller may be justified in assuming that a pilot will follow his instructions because 91.123 requires it, but that does not imply that "wilco" is included in the meaning of "roger."

2−4−3. PILOT ACKNOWLEDGMENT/READ BACK
Ensure pilots acknowledge all Air Traffic Clearances and ATC Instructions. When a pilot reads back an Air Traffic Clearance or ATC Instruction:
a. Ensure that items read back are correct.
b. Ensure the read back of hold short instructions, whether a part of taxi instructions or a LAHSO clearance.
c. Ensure pilots use call signs and/or registration numbers in any read back acknowledging an Air Traffic Clearance or ATC Instruction.
NOTE−
1. ATC Clearance/Instruction Read Back guidance for pilots in the AIM states:
a. Although pilots should read back the “numbers,” unless otherwise required by procedure or controller request,
pilots may acknowledge clearances, control instructions, or other information by using “Wilco,” “Roger,” “Affirmative,” or other words or remarks with their aircraft identification.
b. Altitudes contained in charted procedures, such as departure procedures, instrument approaches, etc.,
need not be read back unless they are specifically stated by the controller.
c. Initial read back of a taxi, departure or landing clearance
should include the runway assignment, including left, right, center, etc. if applicable.
2. Until a pilot acknowledges a controller’s clearance or instruction, a controller cannot know if a pilot will comply with the clearance or remain as previously cleared.
EXAMPLE− “Climbing to Flight Level three three zero, United Twelve” or “November Five Charlie Tango, roger, cleared to land runway four left.”

3−7−2. TAXI AND GROUND MOVEMENT OPERATIONS
Issue the route for the aircraft/vehicle to follow on the movement area in concise and easy to understand terms. The taxi clearance must include the specific route to follow. When a taxi clearance to a runway is issued to an aircraft,
confirm the aircraft has the correct runway assignment.
NOTE− 1. A pilot’s read back of taxi instructions with the runway assignment can be considered confirmation of runway assignment [THIS IS WHERE PILOT'S ACKNOWLEDGING RUNWAY ASSIGNMENT STOPS THE 20 QUESTIONS, sic}
THIS is what a controller is required to do. Nothing more, nothing less. What SHOULD be, or how we WISH it would be is one thing. The above is what IS required.
This is not to say what would be good operating practice above and beyond the requirements. That is not the point of this response.
