I absolutely do not agree with you at all on how useful it is, and I don’t think the usefulness it does have is worth the inaccuracy and confusion you introduce by adding it. If you ran your own ISP, it wouldn’t be the end of the world if you did, but the ISPs today that omit it are absolutely right to. And advertising their services based on it as users are suggesting here would be completely inappropriate and misleading.

And file transfer protocols are anything but standard. They deviate drastically from one to the next. That’s a big part of why it’s not a very useful estimate.
