Why should links always be underlined. An underline draws attention to itself as being something important. Many of the links in my texts are not important but serve as a reference. Underlining a link will only distract attention from the text.

Incidentally, I think it's a strange move. The block editor gives the author maximum freedom to format his text however he wants and thinks it is right. Why a more or less compulsory regulation about the format of the link?
