Each to their own, but for me it absolutely is. The symptom of why that hack happened is the same reason why my agents go haywire every few days and I have to purge memory and figure out what comments have agents left which are degrading my harness performance.
On the flip side, once in a while, what I find is that it did actually note something good and it was increasing the performance. I can't replicate it on anyone else's system but mine.
A lot of it really is memory. I will give up all the gains if it also gives up all the downsides.
