It is a general principle that to avoid using abnormal
condition handling for programmed control flow.
I think it is very unclean to treat ordinary input
like a quit and then distinguish them later.
So I don't think we should add this mechanism.

It is easy enough to do the job using input-pending-p.
You can use

  (catch 'input
    (...
      (if (input-pending-p) (throw 'input nil))
      ...))

if you want to avoid testing input-pending-p at various
levels in the code.
