The review for the change in `src/addrdb.h` needs to take into account the fact that PR19129 was merged before PR17850.
See [[https://github.com/bitcoin/bitcoin/commit/2ad58381fffb33d611abf900b73d9e6b5a4e35f8#diff-4abc2f2dd56fce102a39334bf90b4b4ca0844f6a58de49f35ba659f539e133a9 | 2ad5838]] and D7146.
The best strategy is probably to compare the new content of `src/addrdb.h` with [[https://github.com/sipa/bitcoin/blob/2ad58381fffb33d611abf900b73d9e6b5a4e35f8/src/addrdb.h | the content pf the file after the PRs are merged]].
