Does Filoni dislike Delta squad

I enjoyed the 3 seasons of the Bad Batch, antics and all. However I always felt in the back of my mind these events could've easily been done with Boss, Fixer, Sev and Scorch as opposed to Clone Force 99. We barely get a cameo of them in the clone wars then a depiction of Scorch as the head of the TK training program in TBB. I agree with a lot of the newer canon decisions, but this has always seemed like blatant disrespect to the characters and their purpose. Has Filoni ever specifically talked about them?
