How to avoid zombie scripts and how to remove them safely ?

[LatinGames]

Investigating the "Script Instances" folder of Resaver, I found a large number of Zombie Scripts, which are reported by Rsaver as:

There are zero threads attached to this script instance. 
There are zero stackframes with member data referring to this script instance.
There are zero instances with member data referring to this script instance.
There are zero references with member data referring to this script instance.
There are zero arrays with member data referring to this script instance.
There are zero structs with member data referring to this script instance.

Questions:

1. Is there any tool or configuration in Skyrim SE, which automatically removes them, something similar to "Garbage Collection"
2. When there are many Mods installed, these Zombie Scripts can corrupt the savegame irreparably,  How removes them safely? Rsaver Doesn't

As far as I know, there is no "safe" way to remove information from a save file.
