That's not an interface that has much merit either, it would be nice if we
didn't have to support it and we had the freedom to execute the scripts
directly.

I think all scripts in /etc/init.d/ must have a shebang line and be executable,
and be able to be executed directly. Executing .sh scripts explicitly by sh is
not something I see much value in supporting, Petter expressed similar
sentiment when I poked him on IRC.
