Accessible for development, sure. Developers and hobbyists are willing to pay $500 for an FPGA devkit, and that's been possible for a long time now.

But, more recently (last 10 years), we've seen increasingly-low-LE FPGAs on increasingly-minimal FPGA breakout boards, with no educational subsidies required to make the boards cheap. There are FPGA boards you can play with for under $50 now; and some <10k-LUT FPGA BGA ICs themselves going for $10-$15. That's to the point that it's just "a thing you can choose to add" to a board you're designing, rather than something so precious that it's the constraint you're designing your board around.
