Not really. Before RISC-V, the low end was held firmly by 8051, and at the high end, it was a fight between Xtensa, ARC, M0, and "others", be that custom ISAs or something like legally distinct MIPS.
Now, both ends have RISC-V seeping into them.
And I suspect it’s accelerating quickly. This whole space is hyper cost-competitive and pennies matter, so being able to design whatever you want without having to talk to lawyers or pay anyone anything is a huge win and matters far more than whether something takes 1 instruction or 2.
