I think you can remove comments like this, or leave them to the source code. This doesn't directly help the reader understand when or if to change it. Or, add context here about why one would set this.

Pardon, I just noticed one more thing. This is really about the Context Cleaner, right? not garbage collection per se. I'd probably put these properties under Memory Management instead of a new section.
