There was an argument for disabling Es on ADL: small die size - horrific heat dissipation, and shared L3 with a lack of L2 on the Es, not to mention gimping ring clock by up to 800MHz in some cases.

With RPL Intel changed the way the cores access cache and the Es no longer affect ring clock. In my testing my 12900K on average did slightly better with Es enabled, but I can at least see the logic behind 12900K @ 51P/49R vs 51P/40E/42R. With RPL we can do 56P/45E/49-50R and the cache system changed entirely so there’s generally no merit in disabling them (W10 scheduler sometimes doesn’t handle them well).
