Is there a reason why Str::random doesn't use bin2hex?

[arsel-5lvxa7b1]

Hello! I was going through the implementation of Str::random and found that it uses base64_encode with str_replace that removes unneeded symbols, running this in loop to achieve the length needed. Isn't it shorter to just use bin2hex(random_bytes($size))? Some reason we can't?
