Thousands of coins worth $$$$ had been lost due this kind of user's mistake at least software/wallet developers build for somewhat user friendly that will help to avoid this if possible.
yes, even my self its happen like 2-3 times
because the address of coin hard to remember
and i think is possible in near future and maybe right now the coin need to be implemented new unique alias to make people easy remember it.
and yes there bunch coin out there that using same address like ERC 20 and other coin start with 0x
maybe add "Thenameofcoin" at the first of address can be the option right now for developer of the coin but its really hard right now with bunch of altcoin right there
