I personally did it recently and it was a breath of fresh air not having to worry about cipher suites or DH params or other garbage as TLS1.3's defaults are secure. Although note that I did see a drop of ~2%-3% in traffic after that. I don't directly make any money of these websites (just my personal blog and similar) and most of my viewers are likely to be technical (i.e. not using IE which doesn't support 1.3), so I decided the sacrifice was worth it for another small reduction in needed sysadmin thought+work.
