H.R. 8424: Supreme Court Term Limits & Regular Appointments Act, Taking Aim at SCOTUS

This was my thought upon reading the title of this article - "I think before turning their sights on the courts, congress should be discussing instituting term limits for themselves, prior to projecting on another branch of the government. A little housekeeping perhaps?"
My concern with Term Limit Legislation; will a future congress be able to rescind it? If it happens not only will we dump some folks that shouldn't be there, we'll also lose some trustworthy members.
