Why is automatic restart not enabled in the systemd service file?

In attached service files, there are no Restart option. Why not enable automatic restart by default? e.g. when fuse client crashes, automatic restart may allow user to retry without manual intervention.

$ sudo systemctl enable *.service

We consider all unexpected exits to be unintended and require manual intervention to investigate the causes, rather than allowing them to be overlooked due to automatic restarts. If you need automatic restart functionality, you can configure it yourself.

I see, at least for FileHandle it's not safe to enable auto restart - fh is just a pointer to a heap object, and if restart happens kernel may send an obsolete pointer, but fuse daemon has no way to determine whether this pointer is valid for the current process.
