Yes, since the 'shaver only' labelling did not preclude using the socket to charge a rechargeable razor, I always suspected that nothing about the socket (or its current-supplying capabilities) actually changed, other than addition of the symbol, when they came to be labelled for toothbrushes as well as shavers. However, I could be wrong!Apparently the shaver sign meant you must only plug a shaver in, and not something else with the right plug and the same current draw. When they changed it to a picture of a toothbrush it all became ok.
