I can’t speak for other scientific disciplines, because I don’t know them well enough to have a decent opinion.
Biology as a science should be free to pursue design hypotheses, should the evidence warrant them. Such hypotheses must say something that standard theory does not and should be testable by others who do not share the design presupposition, but who want to see if the hypothesis works.
That’s all.
We should note that plenty of sciences, other than biology, entertain design (intelligent causation) hypotheses. Remote sensing, archaeology, SETI, cryptanalysis, and so on.
