Yes. Sometimes you need to know why a particular thing was done. Recently I had to go back and find out why a particular conditional was added to the code. 10 years prior someone added in a particular conditional for a bug in IE8 (which we no longer support). There was a Jira associated with it. I then knew I could remove this odd logic as it was no-longer relevant.
