Also it is the way preffered by real life PLAAF pilots.
One example,according to the memoir of a PLAAF MiG-17 pilot,the pilot of a MiG-17 can choose the gun(s) he want to charge by using the control box on the top left side of the instrument panel,and he led a damaged Komintang F-86 slip away for not charging the 37mm.

Yes, but does that mean we have a standard PLAAF Mig-15 configuration? For arguement sake..I read there were 30 odd countries that used various versions and setups of Mig-15 including Afghanistan, Albania, Algeria, Angola, Armenia, Bulgaria, Cambodia, Congo, Cuba, East Germany, Egypt, Finland, Guinea-Bissau, Hungary, Indonesia, Iraq, Israel (captured Egyptian examples), Libya, Madagascar, Mali, Mongolia, Morocco, Mozambique, Nigeria, Pakistan, Romania, Somalia, Sri Lanka, Sudan, Syria, Tanzania, Uganda, North Vietnam and Yemen....surely they didn't all prefer this setup?

If what we have are PLAAF examples, maybe new slot Migs with other loadouts and weapon configurations could be a more valid option than changing the existing setup. There were fighter-bomber versions could also carry bombs, rockets, fuel drop tanks.
