Paints Pakistanis in a poor light - puts them in the same bucket as Bhaktora Indians for making spurious claims.
Because at the end - as was evidenced with the F-16 or even back in 71 when they claimed Mirages downed - militaries do document losses at serial number level, even if the information is not immediately public.
Aircraft losses tend to create internal maintenance logs, logistics consumption, personnel consequences, procurement shifts, satellite or ground imagery opportunities, and eventually some archival or investigative record DOES happen. After all even the USSR could not hide many things and it eventually came out.
