Documentation gets obsolete relatively quickly. Code is the source of
truth. A lot of comments in WebKit are either outdated, incorrect, and/or
misleading. Change logs describe a change and thereby a specific point in
time of the repository and wouldn't carry the same issue.
It's also particularly useful to be able to see why a given line of code
was written. Was it an oversight? On purpose? Or perhaps the required
behavior different then and now? It's impractical and unproductive to add
such a comment on every line of our codebase, and that level of online
comment will add so much clutter to the codebase and would make it harder
to read the code.
