Not really, the foundries are on the cusp of fully validating rocket cores on the various processes, and you can just include them in your design like you would a Cortex-M or Cortex-R. They've recognized that 3-5 stage classic RISC cores are a commodity market now, and it's in their best interest to make it as easy as possible to add to your design.
Above those simple cores, we should expect to see more and more RISC-V cores hit the same level of "just drop it in for no licensing, already validated, the pieces like register files are already optimized for the process". BOOM is ~Cortex-A9 perf/gatecount/IPC, which puts it into greater than RPi territory (usable, but not really out crazy). There's still work to be done on the higher end still, albeit, but it's not like you can just go out and licence the highest perf ARM cores anyway (those are Apple's).

ARM has an existential threat, IMO.
