I had the same impression, but support for new sleep modes seems to improve quickly. A few years ago I had a Gen 1 ThinkPad T14 AMD, which still had S3 sleep. A significant portion of the resumes it would come up with some devices not working (e.g. trackpad, fingerprint reader, etc.). I recently got the 5th Gen T14 AMD and the only issue I have is that the fingerprint auth takes a few seconds to come up, but other than that I haven't had any resume issues yet.
