Sockets: Always prepare sets of 5? What is the best way?

Nonsense, I would leave it...

Either I misunderstood him or you did, or I misunderstood you. He wants to connect the sockets sometime in 5 years, as I understand him.

Yes and no. In some places, I currently think that a triple socket is sufficient. Therefore, I would like to install a triple socket but drill 5 holes directly so that, for example, in 5 years I can easily turn the triple socket into a quintuple socket.

But you have to close the two remaining holes again. At least for now... It means that in, for example, 5 years you will have to drill again anyway... That's why I think it's nonsense.

But you have to close the other two remaining holes again. At least for now... That means that you will have to drill new ones anyway in, for example, 5 years... That's why I think it's nonsense.

Yes, the opinion on this is clear. Therefore, I will not do it. Your arguments are comprehensible. But I will have to make an empty box for the clamping, or do you have another idea?

The greater effort compared to drilling now or later, I see in the control of the future sockets. The cables to them should already be laid now. Considering individual switchabilities, this results in quite a tangle of reserves, for which I already see a "multi-socket" becoming necessary just for its accommodation. Compared to the variant "all five ports immediately," I only see you saving the difference between two socket inserts and two blank covers. Clearing the extension cord jungle would be a main motive for electrical modernizations for me in general. However, little is known about what the future holds: in twenty years, we might have many small consumers using a successor to today's USB.

Yes, the opinion on this is clear. Therefore, I will not do this. Your arguments are understandable. But I will have to make an empty box for the clamping, or do you have another idea here?

You take deep flush-mounted boxes and clamp in one of the boxes that are there anyway.
