Of course if it goes really bad(fatal or stroke or something), you just lost years of expensive science education just to test a drug that's not gonna work. Sure it's faster if you get it right, but the if you do the math on doing this as the standard method it would quickly be fae too costly to society.

At least that's my take on why this is perhaps not the most ideal methodology in terms of opportunity cost.

Definitely shouldn't be considered "standard", the value judgement would be left to the inventor who decides whether or not to take it.
