All channel implementations are dealing with a similar concept, and just do
it in different ways to work on different platforms and have different
capabilities. One of the main things that sets Lightning apart is that the
code is very complex, to accommodate the limitations of Bitcoin script.
Sure, you *could* use various layers and adapters to make it work, but
would you want to? I'm guessing most people will want to use something that
is tailored to their use-case and easy to build upon.
