The Boy Scouts of America did a lot to promote Leave No Trace and helped it become a common practice.

It's not appealing to any kind of gendered stereotyping though. It's a quote from the founder of "The Boy Scouts Association".

I suggest you take your complaint to the English language office. In Dutch, that organization would be called "padvinders" (lit. pathfinders, i.e. trackers) which shows that the concept itself isn't gendered.

Because it's a Boy Scout rule?

Your suggested term works, too. But why is it bad that a good concept has a gendered term?

One definition of the term in question:

The non-gendered term for "Boy Scouts" is simply "Scouts" or "Scouting" [1]. So if you need a non-gendered name, just call it "Scouting".

And the word 'scouting' already means "moving ahead of a group to gather information", which makes sense in the software engineering context too.
