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

4) Where the Standard is silent about changes in level, such as 604.3 around a water closet or in a toilet compartment:

Since there is no mention of the phrase "changes in level are not permitted", are changes in level that comply with 303.2 or 303.3 always allowed? Are changes in level that exceed those defined in 303.2 and 303.3 ever allowed in those locations?

Other examples include (this is not a comprehensive list): 604.8, 604.8.2.1, 607.2, 608.2, 608.3, 608.5.2, 608.5.3, 802.4, 810.2.2, 810.5, 904.3, 904.5, 1009.4.1, 1009.2.3, 1009.2.7, and 1009.5.2
