This is not the same as the new suspension. The one in 2015 only affected extension of stay applications (if you want to extend your visa beyond 6 years). Typically people start the extension of stay process well in advance (USCIS lets you start at most 6 months before expiry).

The current one affects anyone trying to file a new petition (including those that are cap-exempt). If someone wants to switch employers they cannot use premium processing, which affects their ability to travel internationally and/or move jobs.
