We're just talking about two copper-lined holes next to each other for each power connection. There were two of those spaced closely together in a recess in the wall. They were close enough I could have touched the metal of one outlet while grabbing onto the power plug inserted into the other outlet. Since my power plug adapter is two copper-plated pins that mated with the holes and had no electrical break like you see on a tip/ring headphone jack I assume the exposed metal is live and the pin is live when inserted.

Perhaps there's a hidden mechanism that enables power after insertion? There was no switch for each outlet. I no longer remember if there was a switch for the pair of them but I don't think so as I was worried about getting shocked. This was in a Belgian hotel I visited a few years ago. Sorry I didn't take a picture.

I have the feeling that you are talking about european style socket with shallower than normal recess, ie. CEE 7/1. These sockets are sometimes used in Benelux countries for RCD protected circuits without PE, and should only be used for Class II devices which usually have CEE 7/16 “EuroPlug” with isolation sleeves and thus there is nothing to touch. On the other hand nothing prevents you from plugging essentially any other european plug in there which then becomes safety issue both because of the exposed live pins when (un)plugging and missing grounding. Similar sockets were (are?) also used in Russia.

This is probably the only case when CEE-style socket is not designed such that it is safe to use with any CEE-style plug that mechanically fits. In general I view the system as better design than BS 1363, because it solves the relevant safety issuess without overengineering and with reasonable degree of backward compatibility.

This almost sounds like an outlet without the cover installed?

Outlets next to each other, still without cover: https://www.entscheider.com/elektriker-und-elektroniker/wp-c...

Maybe even like this (seems to be older): https://de.wikipedia.org/wiki/Schuko#/media/Datei:Doppelstec...

Definitely not normal what you describe there. I'm glad you were cautious.
