"pre-baked sets of bitstreams" is a good way to describe what I expect to be the most likely scenario. In other words, spiritually very similar to ordinary configurable hardware (PCIe cards, CPUs, DIMMs, USB devices, etc)

Don't forget the niche nature of an FPGA, too. They are incredibly slow & power hungry compared to a dedicated CPU, so similar to the CPU/GPU split you find that only particular workloads are suitable.
