This enables usage of the offset_of!() macro in the compiler, through the wrappers in memoffset and then in field-offset.

is the comment still accurate? this crate had the dep before

Btw, unstable_const feature lost, maybe it needed?

Grep for memoffset, there is no results.
Before it was included to enable the unstable_const feature, which <enabled usage of the pointer::offset_from function, but that function is not used if unstable_offset_of is enabled as that directly uses offset_of!().
The offset_of_tuple macro still doesn't use offset_of so unstable_const does something to the public API of memoffset still, but that macro is not used I think neither by rustc nor by any of its deps, at least that's my impression.
In other words, enabling unstable_const makes no sense at this point.
