Getting root privileges is not the end of the road. As discussed before, maintaining access is an essential phase in hacking methodologies, thus post-exploitation is required to not only maintain access but to spread into the infrastructure, to further compromise the system.

This shows and supports the importance of the first pentesting phase (pre-engagement) to protect your client and of course, protect yourself.
Based on the penetration testing execution standard, a post-exploitation phase should go through six sections.
