Nobody in government is going to ask for a revocation. There just isn't the appetite for it. It will have to be forced through, but that's highly unlikely as things stand. At least inside the next two weeks.
If a lengthy extension can be forced, then revocation becomes an option, but there'd be a GE first. It's impossible to say how a new government might proceed.
That said, even if a new government secures the same kind of majority May inherited there's no guarantee for any option right now. Parliament is paralysed.
