ENIG sounds expensive right? Double the cost of your board or w/e? IMO it's no big deal because::
- A: If you want a 6 or more layer board at some places, you have to get ENIG anyway, and solving routing puzzles isn't my idea of fun.
- B: The PCB price is a small portion of the overall price anyway; parts and SMT dominate. So you're paying 2x as much on 15% of the total or w/e.

This just illustrates how different people are: I sometimes make PCBs just to route them! It's by far the most fun part for me.
the only people who gonna use this footprint is hobbists, and they care a lot about cost.
Eh for a hobbyist it's simpler and more robust to just put a connector on the board or use a test clip. I use clips like these: https://www.aliexpress.com/item/1005007622121847.html
