Glyphs 2 plugins future

Will existing plugins for Glyphs 2 support it in the future? Or there will be no backward compatibility when they will be upgraded for Glyphs 3?
For example,
mekkablue/ShowCoordinatesOfSelectedNodes plugin stopped working with Glyphs2, so I had to reset it to 8273ce3 (Updated plugin binary for M1 and Big Sur compatibility) commit, before binary file was updated for Glyphs3 support.

We are trying to keep it compatible for now. And if a new version breaks compatibility with Glyphs 2, we can keep t old version around.
The binary should work in Glyphs 2.
