This in Dubs, many have praised CS for the feedback he provides as being incredibly details and technical (stories have existed of him 'feeling' an issue on the Ducati, going to the pits, they said no problem go out and keep circulating only for the motor to go pop within half a lap)
Gabbarini and Suppo have both praised his technical and development work (as it has been said have others) so the 'claims' about his developing poorly are seemingly incorrect
Personally, I suspect and recall reading that HRC went the Marquez way which did not work so pulled it back a bit, but that is supposition only as have not seen anything official
Edit. The issue with a lot of team mates of CS has been that they simply cannot ride as he does as he uses little electronics when compared to most others, thus when developing I suspect that his feedback is based on less electronics which when they are then used may upset the applecart a little
None of the people that praise his feedback are riders and Gabbarini and Suppo would never say anything negative about Stoner. The only one who can ride the bike he "develops" is him. But I have pointed out before that his best year on both hrc and ducati were his first. That doesn't speak well about his ability to develop.
