Argh, it just happened again with 5.17a!  And it was definitely only
(and all) the prefix key documentation entries which vanished, such as

   ("#" . "TODOs by priority")

Additionally I have been most careful to regularly save customizations
since the discussion above, so I'm now sure that there is a bug
somewhere after all; I just don't know how to trigger it.  Is the
defcustom definition for prefix key documentation definitely correct?
