Real identity is usually a very bad idea for most platforms with few exceptions in my opinion. Wouldn't help Twitter if exchanges get even more personal and the bottom quality content is almost always people whose identity is known anyway.

edit: Anonymous accounts that allow for detachment and people need to learn not to consume media they don't like. It is pretty easy actually. People in the public, even small ones like streamers are putting themselves out there and it can become a problem. But there isn't a technical solution, these are the age old problems of PR. This is why popular people in the public sphere have agencies just for that single problem.

The real name idea is overall pretty bad for numerous additional reasons.
