Excluded admin users from flood control block

Not limiting the number of login attempts for admin accounts creates a significant security vulnerability that can easily be exploited by attackers. This approach increases the risk of brute force attacks, as attackers can try endless combinations without facing any restrictions.
A better solution is to use an IP whitelist feature.

The actual logic that blocks or excludes an account or ip address is done by Drupal Core.

The contrib module Flood Control provides a UI for Core settings and for Unblocking accounts or IPs.

Feel free to move this issue to the Drupal Core queue.
