ETA Questions: Interpretation of the "Changes in Level Are Not Permitted" Requirements

3) Where the standard says "Changes in level are not permitted", but no advisory follows the standard, such as 404.2.4.4 floor or ground surfaces at doors:

Although the Advisory at 304.2 mentions that changes in level that do not exceed those permitted in section 303.3 are acceptable in "required clear floor and ground spaces, turning spaces, and in similar spaces where people using wheelchairs and other mobility devices must park their mobility aids such as in wheelchair spaces, or maneuver to use elements such as at doors, fixtures, and telephones," that advisory is not repeated in all of those sections of the Standards. If the full language of Advisory 304.2 is valid, does it also apply as indicated in the sections it lists at 304.2?

Other examples include: 305.2, 405.4, and 802.1.1

Does it apply in similar sections that also say "changes in level are not permitted" but are not described/listed in the advisory at 304.2, such as 405.7.1 at ramp landings? Other examples include: 502.4, 503.4, and 504.4
