This is the constant problem with issue trackers. You start simple and over a few years various people have legitimate needs that the system isn't solving so they make some small changes to work better. Then one day you look and realize the system is far too complex so you start over with a simple system - which of course doesn't meet the needs of the people above and so they slowly get that complexity added back. I've seen it over an over again, and I expect to see it again because what I need is a simple system, but there are other parties who need various complex things that I can't keep track of.

The simplification above isn't all bad - you often discover that 25% of the complexity in the system isn't needed anymore and so that doesn't come back. However there is always new/different complexity needed.
