The Altera Max 10 devices are also relatively simple to support (flash on the chip, few power rails, etc.)

  This is your job, and it really shouldn't feel difficult. This is really not tedious: the minimum board design for these chips literally consists of just power, JTAG pins, and a clock (if the internal oscillator isn't good enough.) The Gowin FPGAs are available (at a massive premium) from Mouser, just like whatever MCU you are already using. Many are available for <$1-2 in China. Efinix are available from DigiKey, with some SKUs under <$10. All of the Gowin documentation is available on their site with a free, approval-less email login and no NDA, or via Google directly (PDFs, just like Xilinx, even numbered similarly.)

      So just use Google to obtain the documentation? Or a fake email? The PDFs are pretty easily obtainable by title: https://www.google.com/search?q=gowin+user+guide+filetype%3Apdf https://www.google.com/search?q=gowin+user+guide+filetype%3A... https://www.google.com/search?q=gowin+primitives+filetype%3Apdf https://www.google.com/search?q=gowin+primitives+filetype%3A... https://www.google.com/search?q=gowin+gw1n+filetype%3Apdf https://www.google.com/search?q=gowin+gw1n+filetype%3Apdf

        If I really need something I'll go that route, yes. But for something that is just on a "cool, that might be interesting" it's too much effort.

        Exactly! If I need it I will go do the thing and jump through the hoop. If I am exploring, hell no. And, next week, if that thing I was exploring turns out to be useful, congratulations, you just sold 100,000 chips.
