Fair enough, they're probably worth the money it takes to poach them. But trying to stretch the (arguably already tenous) "10x engineer" model to explain why is just ridiculous.
suppose every team needs to do a similar 10 story points of maintenance, like a java major version update from 5 to 21.
if youve got 100 teams, thats about 1000 story points, and if an engineer automated that change, theyve still done 1000 story points overall, even if what they implemented was only 10 story points itself
JIRA has a notion of business value points, and you could make up similar metrics in other project planning tools. The problem would then be how to estimate the value of implementing 0.01% of the technology of a product that doesn't sell as a standalone feature. If you can accurately do that, you might be the 100x employee already.
Like writing a code generator that automates tedious work.
