Track Freeze vs Track Commit

I must be missing something, but now that we have track commit with PT 12., I'm not understanding why getting track freeze in the next version (12.4?) is so important. What advantage does track freeze offer really when we have track commit? Isn't the end result the same? If you commit an instrument track and make it inactive...isn't that basically the same outcome as track freeze? And if you want to re-tweak the VI on the instrument track, just reactivate, edit, and re-commit. What am I not getting?
