Complex effects (without particles) is possible in Synfig. XD Although control in specific scenes is a different issue.
Are there some pixelation in the edge of the spiral? does it come from synfig?
Yeah. Initially I liked how the vectors gave a raster effect in renders especially to make the animation look more traditional styled, but when working with effects they tend to be annoying (even though some breakage did add a few good to the effect).
Usually happens if you use multiple effects at the same time with one object, such as Twirl, Noise, Sphere, etc. But those glitches work wonders sometimes. For instance, I discovered a nice method to make water waves.
It would be interesting to take a look to the sifz file
Sorry haven’t been around for a while (exams ending at 19th). But here’s the Sifz file.

If you remove the blur layer just before the radial gradient it doesn’t create the artefacts made of pixelation.
Great effect indeed!
