I think one problem with this approach is that maybe less scientists will take on fields / topics where the data is inherently elusive or just very hard to get.

I think one problem with this approach is that maybe less scientists will take on fields / topics where the data is inherently elusive or just very hard to get. Could be rare natural phenomena, highly sensitive data, or whatnot. Maybe the collection of data is so prohibitively expensive or specialized, that other researchers are not able to recreate the process accurately enough, which in turn leads to irreproducibility.
