Request to add or update the notification pop up on Core > Posting period page when attempting to close a Posting Period and the Fiscal Year End bundle is disabled similar to the message that normally pops up for the monthly bundles being disabled. Current FY message asks if sure you want to close FY. In testing did not include warning for Monthly or Fiscal bundle being disabled when June is closed.

May also be helpful to add for Calendar Year End bundle (all applicable SSDT bundles)
