It will never go away because you can't guarantee constant time algorithms will be implemented as such when transformed by a JIT.
If machine code can issue the necessary hints to the hardware to skip all time-variant optimizations, why couldn‘t the same work for a WASM runtime?
It could, but you need a lot of work on a lot of layers, possibly routed through an entire standards committee, to get it done. If it ever happens it's going to be a long time.
