This situation is not the same at all. The CSR might mangle a name in latin script but can at least attempt to pronounce it and will end up doing so in a way that the user can understand.

Add to that that natives of non-latin languages are already used to this.

For better or worse, English and therefore the basic latin script is the lingua franca of the computing age. Having something universal for internation communication is very useful.

FWIW, proquint encoding allows you to pronounce any sequence of bits, though the need for pronunciation eludes me, just copypaste it.
