You can simply add glsl filter as often as you need it, so why multiple passes?
How do you envision this to work?

• (most) filters multiple times
  
• (most) filters only on frame sections

-> had no problem here using multiple GLSL filters,....
You need to use "Filter Queue" instead of the default "Filter Order" to add multiple instances,...
read: [INFO] About Vapoursynth Filter Order/Queue
Hybrid allows to add:

• (most) filters multiple times
  
• (most) filters only on frame sections
  

I'm also working on allowing to apply (most) filters only on parts of the image, but so far I only had time to add this for 'Levels'. (I mainly have to adjust the GUI to support this, the background code is already implemented, but I haven't found the time to add this). Also this is more of a 'gimmicky' feature for me as nobody required it and I sometimes use something likt that to see how different denoisers act on a source by dividing the source in X sections and filter each section with a different denoiser.

that the preview works fine, vspipe info works fine, but encoding using:

fails with:

y4m [error]: bad frame header magic

Wild guess is that those shaders only work if there is an acctual display.

Since I don't think this is a bug in Hybrid, I opened an issue entry over at https://github.com/Lypheo/vs-placebo/issues/17 to see whether the author of vs-placeco can say anything about it.
