I can confirm that the banwave was focused primarily on people altering their Trainers, BP Amounts, Festival Coin Totals, etc. I have a copy of Sun and Moon that have each been altered with PkHex, the Sun copy only has injected Pokemon and nothing else. No save states changed, hours, coins, or things of the sort. Meanwhile my Moon copy was altered to have a different gender, bonus BP, and extra Festival Coins. The only account effected by the ban was the Moon account with the edited trainer info.
Don't worry about having injected Pokemon or what might happen. So far the account with only injected Pokemon is doing just fine.
