If CCAs can be used for dogfights in case furball happens, I don’t see why they carry the point defense missile either. I think that the bulge hides something more exotic but we won’t know for sure until more images leak.
Next gen short range missiles could potentially be far smaller and capable of intercepting missiles, similar to APS for armoured vehicles.
I don't see much point for shorter ranged missiles when it comes to 6th gen which appear to be stretching the range of engagement while achieving similar or better P(K) than previous gens. However, even if we can apply this theory to J-36, the J-XDS may still be a dogfighting capable aircraft. It may not be what it's intended for but with the design goal of being able to get closer for a shot, even PL-10 equivalent missiles may have a place with the J-XDS.
Having said that, I think we should expect 6th gens to approach this entire air combat philosophy with entirely revolutionary equipment. PL-10s barely have a place with 5th gens. 6th gen with high end UADF, 5th gen, 4.5 gen and smaller CCAs, there are just too many shooter nodes in the network that have guns and short range missiles. If J-20 goes into a fight without a gun, we should expect J-XDS to go without PL-10s. Wasted room and weight to be honest.
J-XDS should be viewed as J-20's successor and J-36 as an entirely new concept - fast and relatively agile A2A focused shooter platform.
