It's a great time to be into flashlights. There are a zillion fantastic models to choose from. There are so many, in fact, that if I decide I need features X, Y, and Z, there is no need to settle for only X and Y. It's easy to find a light with all three.
In many cases, of course, Z = tail standing!
I just bought a handful of the new BLF-348 flashlights. The 348 is a single-mode, 50-lumen, 1xAAA, stainless-steel, tube light. It features a high-CRI, 5000K Nichia 219 emitter. It's a pretty cool light, and at $7 a copy, it makes a great holiday gift.
So this week I have been testing mine. It doesn't have any throw at all, but it's great for close-up work and journeys around the house. When I used it for my late night lavatory visit, however, I found myself wishing it could tail stand. No problem. I just leaned it against a tray in the drawer.
As others have mentioned, tail standing is not for every light. Some applications are hindered by lights that tail stand. Other than those specific applications, however, I don't see any reason why all my other flashlights should not tail stand.
I wish the BLF-348 did.
