But I am suggesting an alternative to your second point. When FPGA boards become available to more people, the tools will automatically come. Note that, the open-source tools can be built by software professionals, even though they might be amateurs in hardware design.
Thee's already cheap ($50 and less) FPGA boards. But all FPGAs are proprietary, there's no available documentation on the internals, the bitstream, and many other things one need to create 3.party/open source tools.
And I also suspect they're hard to impossible to reverse engineer.
