For this kind of stuff, I'd rather have an eventual harness a bit like
this: https://github.com/ferd/start_wrap

This thing uses a supervisor bridge to supervise your `main/1` function
and then you're able to ship a release using it, giving you the simple
part about an escript, while having the ability to ship and boot OTP
applications along with it.

You can eventually move to a more proper release fairly easily as soon
as you OTP-ize all you've got.

It's still pretty damn unusable at this point, but this was a proof of
concept I quickly hacked together back in March and had forgotten to
share around.
