Yes. It was some update when holes with 0% were remaining between relogs. That time it was not spawning subsurface. Now holes disappear, I can confirm it. So possibly, relog works again. But I wouldn't relay on it. As it looks like they made regression in between patches and will fix it.
Yes, I remember too when subsurface deposits would stay at 0% and then NOT disappear, they were so annoying because there was confusion between the 0% subsurface deposits that stayed between local contact and the other subsurface deposits that you had to finish extracting instead, but even then, I'm sorry to contradict you, but I remember that they still regenerated anyway, they always regenerate, even when they are not fully extracted, they still regenerate, I don't honestly remember if in that case instead of going back to the main menu you had to instead exit the game and restart it (as with HGEs) but I remember very well that they regenerated.
For now it works, in the future we don't know... I honestly am not a very experienced miner or even a very passionate one, I just did it to try it out, to relax (mining is very relaxing... almost asmr

), but it is not one of my main activities.
