[Fontconfig] Xft with multiple DPIs/multihead doesn't support different DPI

In my fontconfig/conf.d, I can specify fontconfig XML which states a given
DPI, but I can't specify this per-head.
I'm running multihead on monitors with different resolutions, and my choices
are huge fonts on the lower-resolution monitor and normal sizes on the
higher resolution monitor, or unreadably small fonts on this hi-res monitor
and normal size on the low-res monitor.
xdpyinfo | grep inch correctly tells me
on :0.0: 157x157 dots per inch
on :0.1: 94x94 dots per inch
xrdb -query | grep dpi correctly tells me
on :0.0 XFt.dpi: 157
on :0.1 XFt.dpi: 94
farad:~/.config/fontconfig/conf.d$ grep -i -A2 dpi *
19-DisplayProperties.conf: <edit name="dpi" mode="assign" binding="same">
Note that without the 19-DisplayProperties.conf setting the DPI to 157
explicitly, the menus and other fontconfig-rendered text on my hi-res
monitor appears to be defaulting to the historic 96 DPI setting, and are
therefore tiny, because they're approximately 60% of the size they ought to
How can I tell fontconfig to use the correct DPI on a given head?
(I tried to open this as a bug and was directed here instead.)
