In other documents too. And very repetitive.
I don't need a link to Wikipedia every time "PoC" is used. Or to an online man page every time strace(1) is mentioned.
I get it that a documentation can have more than one "entry point", and hyperlinking all occurrences solves that.
But I think assuming certain audience leads to a document that is more effective. You don't explain addition in university-level textbooks, to make it easier to children from primary school.
This product is simply not for people who hear of strace for the first time.
