If you sit someone who doesn't know How Links Work in front of some text with an inline hyperlink in it, then try to get them to copy it over to another place, you end up wanting to get to this default pretty quickly. "Right click copy link address" is real unintuitive. I've never wanted the text formatting itself to come over, bold text and headings and whatnot, but since that lives in about the same conceptual space, it's a casualty of design.
