[CentOS] vsftpd rejects users set to nologin

I updated to CentOS 7.6 and something must have changed in the base OS 
setup  that prevents vsftpd from allowing logins for accounts with 
/sbin/nologin as their shell. I had to add that to /etc/shells so that such 
accounts could FTP again. That file is in the setup package. Did it include 
/sbin/nologin before? I don't have anything in my notes from setting up the 
system last year about changing that. What's the history of shells listed 
in /etc/shells?
