Sure, on github it will (still) get the most attention, but perhaps another repository outside the US is a better fit.

You could also create a text document instead of a software that details the mechanism used to fool other MIDI decoders and publish only that (for now).

Finally, familiarize yourself with the Art. 6 Software Directive (2009/24/EC) / §69e UrhG — decompilation for interoperability. It may be your ticket for a legal status in Germany/EU.
