Shahed shape is dictated by the need to sustain very high G and aerodynamic forces during the launch from a truck which in turn allows for a very fast deployment. Anything more aerodynamic will imply stronger, more expensive frame and less payload.
Shahed has sufficiently bright IR that even a basic seeker works. To keep the cost low no efforts were applied to minimize the signature.
It is fascinating how well designed Shahed was for its intended purpose of being the cheapest mass-produced platform that would saturate any advanced air defenses while hard to track launch site. However, with appearance of cheap mass-produced counter-measures it may no longer be optimal.
