Please, please, please still release your source if you don't mind! Especially for "random hacks" like a home brew bridge!
You have no idea how many tiny repos I have used for reference with those types of projects! In many cases your code might be the only working example.
You can put a big disclaimer in it, declare it a PoC, and just ignore issues if you'd like - the code doesn't even have to still be working, it's still cool and helpful!
