Nonprofit pricing for Purview and Defender suites for business premium

I'm wondering when the Purview and Defender Suites will be added to the nonprofit pricing sheets with the nonprofit discount.  E5 Security was an available add on to Business Premium for a couple of months before it switched to the Defender Suite for Business Premium.  Now clients with the E5 Security add on are left without a discounted option to go forward as Business premium has been removed as a prerequisite.
