But if i use PhantomData<T> then its not Send + Sync and if i remove the PD then it errors parameter T is never used.
Signed Extension does require it though.

The SignedExtension trait requires it, i did not check why.
The new TEs will also require it.

If you would just kept the bounds here, it would have been enough.

But we can go with the phantomdata trick.
