Except that, particularly the max-weight ones, mean that developers can be expected to use this as sentinels in code using ICU, which would preclude their use for other things?

Which makes them more like “reserved for use in CLDR” than “noncharacters”?

I would especially discourage any web browser from handling
these; they're noncharacters used for unknown purposes that are

I don't expect "handling these" in web browsers and lamebrained utilities. I expect "treat like unassigned code points".
