Post subject:  Downgrading my plugins can corrupt xcf files in Gimp 2.99.18+

In Gimp 2.10 my GEGL plugins fully break presets if a drop down list loses a setting or if a double (1.0-5.0) is changed to an INT (1-5) The same thing happens in Gimp 2.99.18+, but if a filter is non-destructive it will corrupt an .xcf file. This is not a bug, its just the logic of GEGL.

If you use my Gimp plugins in Gimp 2.99.18+ - everything will be fine unless you downgrade a GEGL plugin with a drop down list. For example if you are using my bevel plugin from late 2023 and you downgrade to the early 2023 version, an xcf that used it as a non-destructive filter will break until you update back to the latest version. Upgrades won't break anything but downgrades will.

I have no interest in breaking plugin presets of mine in my main branch, but I may release a seperate branch of my plugins that break presets and make sure the user is informed with a warning. No one accept people who intentionally downgrade my plugins need to worry about this.

If it breaks presets in Gimp 2.10, it will corrupt an .xcf file and break presets in 2.99.18+
