The red CEE 32A plug was a good interim choice. These are probably the most frequently encountered 32A sockets, certainly in Germany and Switzerland and there is a commercially available adapter to the red 16A CEE (even more common). It is no problem to go to a 16A blue plug ("Camping plug") either. The blue 32 A plug ("Commando plug") is not permitted in Switzerland e.g. The only problem is, that you should remember to set the charging rate in the car to match the adapter yourself. Tesla and others probably expected that a new standard would soon establish itself, so no pig-tail effort seemed warranted at this point in time and I am inclined to support that view.
The connection then to e.g. new Mennekes or its French-Italian competitor will be another matter as then the signaling between car and charging station has to permit among other things more than the current low default currents (10A in Switzerland, 16A in Germany).
To Mitrovic: I saw the new UMCs in Zurich. The plug remains the red CEE 32A plug. A bit more compact, but not that much. The cable itself is still about the same gauge.
I would favour a new UMC with the capability of handling the signaling also upwards to a new norm Mennekes for full compatibility and additional "pigtails" to CEE reds and blues, setting the proper Amps. Even with new standards, versatility is likely to remain important. Some providers view the "charge point market" in the spirit of mobile phone companies, with monopoly positions on the best parking lots, reserved for those paying base tariffs on top of direct charges or additional whopping "roaming charges" instead. Standardization plans are loaded with spurious safety arguments to create and protect just such markets.
