Agreed, using outdated built in hints and diligent logging does cause a minor annoyance (minor as it can be filtered after verifying the incident), so there is merit in updating even if automatic updates might not make sense.  For example, an unfiltered log from a production resolver of ours would like to say the following :)

i would not say that... it's better to use builtin hints file than having
outdated hints file.

But if someone does care about hints file, it's better to have current
version, when the builtin one is older.
