> Who decided copy+paste should copy styling/formatting?

I would say, 1980s integrated office appllications for the Macintosh, like ClarisWorks.

> It makes absolutely no sense that anyone would want to transplant styling/formatting into an email

It absolutely makes a ton of sense: often you want to copy text containing bullets, bolding, italics, underlining and ... oh: tables?

There are times when you don't want the formatting, like for instance when you just want to quote some passage of text, without quoting its 24 point font.

It is essential to have a command to paste without formatting. You need it both ways.

In 2022, can't you get an e-mail program whose editor has paste with and without formatting?

Yes, you can get such an editor, but it is annoying that this is something you cannot rely on the OS to consistently do.
