I agree overall but that's a weird comparison with the tag connect. It's not meant to be small, it's meant to avoid soldering a header down to the target board for programming. It's useful for Z-height or cost savings, not for XY savings.

Sadly, it's not uniquely useful for that either.

I can solder a set of pins (or pogo pins) on a .100 spacing and mate into the .100 header holes. Or I can offset the .100 holes very slightly so they friction grab a .100 2x2 male header in the holes.

Or I can buy a breakout board that does the same thing for $7.00 for 2 rather than $50 per cable like Tag-Connect: https://www.pcbway.com/project/gifts_detail/PogoProg_Model_D...

.100" headers are hard to beat for general effectiveness.
