Application Administrator: Additional license usage for Partner Organization companies

Summary:

Hello Everyone,

Want to know what are the implication of not having Application Administrator users for a Partner Organization company.

We don't have any FullAccess user created for our Partner Organizations and we handle them using our Internal user profiles to assist them.

Since SuperUser profile will be removed in 25C and we don't want to waste any license creating FullAccess users in the partner organizations(we have 100+ companies and creating 1 FullAccess user for each company will cost us 100+ license).

we want to understand if there are any issues we might face if we don't have any FullAccess user for the partner organization as we don't need one as per our current requirement.
