I see now what you mean. This can be easily implemented with the
following patch. So you can set `clear-message-function' to a function
that returns a non-nil, and the echo area won't be cleared.
Such predicate function could contain a complex logic, but for testing
you could use just:
(setq clear-message-function (lambda () t))
