If an enemy country has no more troops or cities left and you control ALL their homeland cities you should be able to claim all their leftover provinces and make them yours.
Examples:
Country A has taken all the cities of Country B, including Country B's homeland cities and Country B has no troops left- Country A can claim all the leftover provinces.
Country A has taken all the cities including all homeland cities of Country B, but Country B still has troops left- Country A cannot claim all of Country B's leftover provinces.
Country A has taken all the cities including all homeland cities of Country B except one which belongs to Country C and Country B has no troops left- No one can claim the leftover provinces of Country B and have to take over manually ( Country A has to get that one homeland city of Country B which is controlled by Country C to claim the leftover provinces).
If the insurgents meet the requirements to claim a country's leftover provinces then they will not be able to claim the provinces.
Why this feature will be useful:
More Realistic- A real nation would surrender if all their major cities and troops are lost.
Quicker Games- Many games are made unnecessarily longer because of leftover provinces
Accidental Wars stop- When manually taking provinces two countries may get into accidental wars and problems occur
