Intel are of the opinion that hybrid serves no purpose in servers, as you're typically not going to have a particularly non-uniform workload on a server; they tend to run at fairly steady-state load levels, with a lot of simultaneous tasks, so you're not generally going to have unloaded/unused cores. Heterogeneous compute isn't super useful if you never have an opportunity to clock/power gate some P-cores; AMD and ARM tend to agree with them on this point, too.

That said, Intel do have a pure E-core Xeon CPU due out in 2024, probably with some frankly ludicrous number of cores, targeted at the mobile game market; quite a few mobile games for Android run entirely in the cloud, with a dedicated core per simultaneous user, then stream the result down to the user's device; prevents cheating, saves device battery usage, and means you get the same experience regardless of your device's performance. (Personally I don't like it, but that's what they're doing...) and these are targeted at that.
