Collation migration for ghost@5.x + mysql 8 upgrade

I migrated successfully to ghost v5. For the same, I upgraded mysql from 5 to 8.0.
And ran the alter commands for collation as mentioned here. Now the collation for the tables have been changed to what’s recommended(utf8mb4_0900_ai_ci).

But I checked the default collation for the ghost_prod database is still the old one(utf8mb4_0900_general_ci) so any new table created will have that default collation, not the one recommended(utf8mb4_0900_ai_ci).

Can this create a problem when I upgrade ghost in future?
Do I need to take any action now?
