it depends...on A LOT OF THINGS!!
depends on the problem, on the need for doing such a thing, the money a country can spend on sth which you're not even sure if it can solve the problem...and then at the end, its not in our hands, its the authorities who decide.
for all the diseases that we see these days, its extremely useful. and i find genetic mapping SO not a problem unless someone misuses it. which is ofc another issue. it can do A LOT OF GOOD...the harm happens when it's used that way!!
