There are some good points I can see:

* Knowing which version of the installer you are using, so you know which versions of what are gonna be installed by default, sometimes the installer itself will contain bugfixes (but not always).

* Knowing what is the minimum patchset applied to a system. You can check the etc release files and get a summary of the updates applied, eg.: if you see release 10.2 you will know that at least all of the patches up until 10.2 were applied. This one is very useful if you are debugging a system and want to get an overall idea of how up-to-date it is, if you are debugging a system that it's behind the latest updates, you should always consider that as a possible cause, knowing which is the point release allows you to reduce the diff/bugs you will be looking at.
