What information was incorrect, unhelpful, or incomplete?

Incomplete. Safari added support for "brotli" compression and decompression with CompressionStream and DecompressionStream in 18.4.

What did you expect to see?

There should be another line item in the table for "brotli" compression, showing it available in Safari 18.4 and later.

Do you have any supporting links, references, or citations?

Thanks for reporting, verified with this JSBin in Safari 18.5.

This format is not yet listed in the spec, see: whatwg/compression#34

@wmpjohnston Would you like to open a PR adding a subfeature for the CompressionStream and DecompressionStream constructors below? 🙏

Now it is listed in the spec.

I noticed that #28274 has fixed this issue, so this issue should be closed.
