Not at all, I was only asking. And yes you can absolutely do this with dice and coins, in fact I have done so before; but I have discovered this trick on my own and I'm not aware of other methods doing so.
About the dice comparison, I think tiles are more accessible and less prone to biases, which is why I picked this method at the end (it used to be coins). It is true that you need to print & cut the tiles, but you're going to need a printer for the wordlist anyway, so I like that it is not introducing any additional requirements.
At the end, people will use what they have according to their preference, and since the biases I mentioned are not large enough to create exploitable security risks, it's more a matter of polishing & optimization.
