A little know feature I found and heard at least one person talk about online is 2FA autofill support. With every website seemingly requiring 2FA browsers like Chrome can now autofill the verification codes from iMessage.
Only other thing now, IMO, would be 3rd party support for the native Passwords manager as the iCloud Passwords browser extension is awful.
