Personally, I wouldn't bother. They are old and other plug-ins provide the same functionality or better.
But no, it won't hurt for you to install them. However, if you're just installing the 64-bit version of SONAR, then most of those older plug-ins won't work. They will only work if you install the 32-bit version of SONAR and use that.
