I am here to do a request/suggestion that will most likely be rejected, so it is fine if it does get rejected.
As you may or may not know, Universal Electricity has been growing more and more popular and used by more and more mods out there now. My goal for Universal Electricity is to create an API that anyone can use and will act as an open source API for energy. I am here to suggest that maybe some time in the future IC2 could implement the UE API to become natively compatible with it instead of just a converter. This should be possible code wise as the IC2 energy network works similar to Universal Electricity's framework.
Note that doing this does not make IC2 dependent on anything. IC2 will still work at it is now but will just have the ability for Universal Electricity mods to power its machines and such.
This suggestion is kind of far fetched and requires some work, but I hope the IC2 team would consider it as this compatibility will bring a lot of ease to Universal Electricity mods as having every single UE mod be compatible with IC2 is a lot more tedious than getting IC2 to be compatible with UE.
