>You're pretty much out of luck if you need more than an iCE40 UP5k.

Lattice ECP5 (which goes up to 85k LUT or so?) and Nexus have more than decent support.

Gowin FPGAs are supported via project apicula up to 20k LUT models. Some new models go above 200k LUT so there's hope there.

Yeah I've used yosys / nextpnr on an ECP5-85 with great results - it's pretty mature and dependable now.
