I was thinking it would be a good idea for international matches not to be included in the missed matches count for loaned players. A team in participating in international competitions might need to loan 1-2-3 players to create depth and save stamina for its starting line-up. An average youth can never be expected to play at international level, but he is surely expected on the domestic level, especially if the domestic league is relatively weak. Indeed, a loaned growing youth is expected to play only a game a week, playing 2 per week should be a bonus, not a requirement, especially if his real team ain’t playing at international level.
I think it is better as it is today.
If you have to loan many players probably you wont go further in international games.
