But the entire point is to move away from subtle clues and use experimentation to show something clearly and as definitively as you can. This may take time of course, it isn't an instantaneous process. But isn't the onus on the proponents of ID to show how credible their science is rather than on the whole rest of the scientific to suspend their incredulity.
Evidence quite often is ostentatious, look at the screens for mutants in drosophila. If there were not so many striking examples of embryonic lethal and homoeotic mutant developmental genetics would be a lot poorer for it. In many cases it is the ostentatious phenotype that allows us to detect subtle genetic changes.
