How practical (not semantically) is the fieldset tag useful when using XMLHttpRequest to submit forms?

Question

HTML

I read the specification several times, and did not find an answer for how practically I might need it. If I just need to group the inputs, then I can do it with divs, why do I need a fieldset? Are there any other benefits? Or is it just a relic of the time when there were no front-end frameworks and so many javascript requests from the client (and not the standard HTML form method=POST).

Answer 1

A relic of time
Just like <main>, <section>, <header>, <footer>,
By default, it has a nice outline and a nice feature like legend
