Based on their findings, Bornmann et al. suggested to concentrate funding on already highly-cited researchers and research groups ("A concentration of resources on these elite structures seems to be practical especially for the life sciences and health sciences"). This is already happening, to some extent, but if the authors' offer is to be accepted, I suspect highly-cited authors will forever remain at the top, simply because they will get most of the funding.
Now, citations don't exist in a social vacuum; despite the tendency to see them as "objective" representations of papers which have influenced other scholarly works, they are affected by factors like the paper's publishing journal, personal connections, coverage of the paper in the mass media, and more. Bornmann et al.'s recommendation might cause funding agencies to end up giving their money to the most popular, connected researchers, who are already well-established in their discipline.
