I took two semesters of mainframe classes (COBOL, JCL, DB2, etc) as electives, in 2015-16. I wouldn't want to do that full time (though the jobs are there and it's an applicant's market), but it was a great experience. So much different than all my other CS classes, and gave insight into an important part of IT that isn't really taught anymore.
