The HDMI to VGA adapters have always been as ropey as hell on the RPi,
in fact they were never particularly great even on the OLPCs back in
the day either.
They're also very variable from device to device so it's very much a
case of it may or may not work but we don't really get a lot of
reports either way these days TBH.

I figured that was probably the case. The only thing of note I see in
the logs is:
Feb 16 00:01:21 fedora kernel: of_clk_hw_onecell_get: invalid index 15
Feb 16 00:01:21 fedora kernel: [drm:vc4_vec_bind [vc4]] *ERROR* Failed
to get clock: -2
Feb 16 00:01:21 fedora kernel: vc4-drm soc:gpu: failed to bind
3f806000.vec (ops vc4_vec_ops [vc4]): -2
Interesting that I don't see the issue on minimal.
