FtpWebRequest.UseBinary does not work since 2007

Question

Hello,
I've been working recently with FtpWebRequest and SIZE method. The FTP server that I'm using requires using binary mode. Unfortunately, I'm not able to use GetFileSize via FtpWebRequest.

I've found out that the Microsoft team is "well aware" of this limitation: https://social.msdn.microsoft.com/Forums/en-US/0c38814e-d8e3-49f3-8818-b5306cc100ce/ftpwebrequestusebinary-does-not-work?forum=netfxnetcom

Out of curiosity, has anything changed since 2007? I'm currently using dotnet 6.0.400.
