Absolutely, but this is a classic diagram of what is sold under the name "electronic transformer" for lighting.

I did not say the contrary...

For LEDS, you are absolutely right.
Originally these transformers are designed for halogen bulbs and their main advantage is to be able to provide high power in a small volume and with low heat generation and a limited price.

In fact, the whole problem comes from the fact that we are trying to replace a halogen bulb with an LED bulb without other modifications to the luminaire, whereas it is the couple {transformer, bulb} that should be replaced.

Criticism is good if added to some compliments.
