I do think it's big. What you see on top500 is the high end of the market, the big bulk is in small to medium sized clusters or in cloud infrastructure where people rather care for benchmarks like requests per second of some specific servers. There again memory throughput, non-vectorized performance and cores per dollar are probably the most relevant characteristics of a processor. And those who chase to have the highest flop numbers have switched to accelerators and custom chips anyways.
