Why do some people redirect with 200 status?

Question

Computer networks

What are the pros and cons?
On the eye faster like a redirect passes

Answer 1

only 30x redirects
when you need to hide the very fact of a redirect from a PS or from a browser, tricks are used using js or html refresh

Answer 2

I'm not sure if this is correct. There are well-defined response codes. https://ru.wikipedia.org/wiki/%D0%A1%D0%BF%D0%B8%D...
Most likely, not all clients will adequately perceive a redirect with a status of 200.

Answer 3

what about an example?
200 cannot redirect, by definition, the
maximum is 201 any

Answer 4

Are you sure that this is not a 302 redirect to a custom page, for example, 404.html, which, accordingly, returns 200 - because she exists?
The described example is loved in Bitrix by default
