Why not fix this issue? Could someone give a comment?
cause I found it's easy to do.

I also wonder about this. How can I re-create the session? I want to logout current user just before logging in the new one:

// if some user is already logged in destroy his session
if (!ctx.session.isNew) {
   ctx.session = null;            
}    
// login
ctx.session.userId = userId;

Can't getter create new session automatically if necessary?

I tried to do it like this:

ctx.session = null;
await KoaSession(ctx.app).call(this, ctx, next);

But it will throw TypeError: Cannot redefine property: sessionOptions

Not sure if this has been added, but I can't find a reference in the docs. I also have the same use case of destroying/recreating a session in a single call.
