The 24156986 is semantic though; the ids are assigned sequentially to submissions. Early submissions have tiny ids like 495. So they are at least as meaningful as bug tracker ID's or version numbers.
Now, it is true that version numbers etc. could be more meaningful. Jeff Atwood wrote an old article about the "infinite version" in Chrome, where the version number basically doesn't matter until you're checking to see if you're up-to-date. Personally I've switched to using dates / times in my ID's. HN could do that too; an ID like 2020-08-14-10-12-13-99 is longer than the current ID's but not by much. But overall it seems hard to draw a line in the sand where dates are semantic and version numbers aren't.
