use default features for sp-runtime again implies that we will have parity-util-mem in the dependency tree? 😵‍💫

Sadly it seems that way. The issue seems to be that the std feature of sp-runtime ensures sp-io/std is used. If it is not then you get all the no_std wasm stuff.

So we need to use a dependency feature for parity-util-mem instead of std, or go the whole hog and remove the parity-util-mem entirely: paritytech/substrate#12658

All right, I guess it's worth waiting for paritytech/substrate#12658 before doing a new sp-core release then?

I think so.

From my side we are planning a new ink 4.0-beta releases this week which would require a new cargo-contract release which depends on both sp-runtime/core and subxt. However for the sake of expediency we may have to require to install from github rather than crates.io.
