Sure, there were questions, but why not? Friendly questions. I travel in and out a lot,so I'm used to interacting with immigration.

At some borders, Thai immigration might like you to spend at least a night or two outside of Thailand before returning.

However, with the DTV being so new, it's unlikely any officer will even make the assumption that a DTV holder is going to be doing a same day border run.

Whenever I leave Thailand by land I always go by car and thus I always drive across the border. As a result, officers know I can't possibly be going only for the day as no one goes to the trouble of filling out reams of forms to only drive a few Km and come back a few hours later.

It is and I can attest to that. I've already made a re-entry by land. However, I didn't do a same day re-entry and I probably never will (except if the Myanmar borders reopen as some of them, specifically Myawaddy only allow foreigners to spend the day there unless you have a visa).

I assume, following the reopening of the border to foreigners (whenever that is) the same rules will apply as they did pre-Covid.

The bus station, with services to Thailand is conveniently located in the center of town, specifically, right next to Vientiane center mall and across the road from the main market.

Speaking of using the bus, depending on your destination inside Thailand, pick the right bus.

You can choose to catch a Vientiane (Khamsavath) to Bangkok train as well.

For buses, there are services from Vientiane to Nong Khai, Udon Thani, Khon Kaen and Bangkok.

The Bangkok bus runs overnight.

If you want to fly either to Bangkok or Chiang Mai/Phuket etc. you'll probably be flying out of Udon Thani or Khon Kaen.

Therefore, catch the appropriate international bus to one of these two cities and then take a taxi from the bus station (either Udon or Khon Kaen) to the respective domestic airport.

Obviously, to reiterate, a foreigner can't enter Thailand via a locals border crossing. Those are only for citizens of Thailand and the neighboring country.

However, such border crossings tend to be located in more remote areas anyway.

Simply look up which borders are international (Nong Khai-Vientiane, ie the 1st Friendship Bridge being one) and you'll be allowed to enter that way.

They won't ask for any documents from the initial application but I would recommend carrying 20K Baht in cash as that may be asked for, though it's rarely requested.

Huh? Since when do you have to fly out? You can use any international land border, except for the 3 borders (out of 4) with Myanmar that are currently closed to foreigners. All other land border crossings are open.

They re-opened during the course of 2022 following Thailand's reopening after Covid.

The only time foreigners were required to enter Thailand by air was during Covid.

Why? I've never heard of a visa that requires you to enter by air only.

Except for visas on arrival in certain countries that can only be accessed if you fly in, or in the case of Myanmar where foreigners can only fly in (land borders being closed) almost all other countries allow foreigners to enter by any international border, Thailand included.
