I'm sorry but those links are no good argument to me.

I've already commented on the fact that MariaDB service unit is 173 lines of ini-style configuration with most of the lines commented for example purposes.

So I'd still gladly trade many lines of bash for hundreds of lines of ini-config.

And sure some projects still depend on shell script wrapping, I myself did for many python services that I run in virtualenv. But I learned more about systemd and eventually could get rid of all shell script wrappers.

But even in a worst case scenario where some project might have to use shell script wrapping, it's still better than ALL projects using 100% shell script.
