A similar approach as the last one should work, the problem I was having is
that to print the binary string from python you have to decode it, and
latin-1 seems close to right, but it puts a bunch of extra bytes in it that
lead to a bad png file. I feel like this worked in Python2 with StringIO,

you probably figured out the "import io" and "f = io..." line are not
necessary here.
I couldn't figure out a reasonable way to use :results graphics link
that didn't result in repeating the filename more than desired. These
also both work, but seem to both require repeating the filename twice.

I think you can use something like this:
#+BEGIN_SRC python :results output file :var fname="test.png"
import matplotlib.pyplot as plt
import io
f = io.StringIO()
plt.plot([1, 2, 3, 17])
plt.savefig(fname)
print(fname, end='')
#+END_SRC
It is in Python3.

That was my starting point, but the resulting link is prefixed by ':'
Perhaps I should upgrade org.

For this, you should try updated header arguments like ":results graphics link"
or ":results file link".
