My comments are strictly about HF, and on HF grid squares are not as widely used.
Well, CQ has something called the "Field" award where the "Field" is the first two letters of the grid.
Believe it or not last Sunday, before I saw this thread, I had configured JTAlert to alert me of new HF grids. I'm almost hitting the wall with my current station, and since I don't plan any "investment" in it, I'm looking for other "challenges" where the current station can still be useful, in addition to "standard" DXing.
I already qualify for the Field Award. So I upgraded my eQSL membership to apply for it, since I don't do paper applications and mailings. Never mind card checking, I have very few cards.
As "luck" would have it, of the 4 CQ awards via eQSL, this one is still processed offline, so for all intents and purposes, not available to me.

But I did get a truckload of eQSL awards, so it was not all bad.
