We are near to that stage that bitcoin is totally worth a lot of money and faucets can't attain to give hundreds to thousand of satoshi's but they will be ending up giving 1 satoshi and even can go with decimal point.

And what do you think if the value of bitcoin is really high and 1 satoshi = $1? It makes sense that these faucets will keep on adjusting their rates.

In everything that uses bitcoin for payments will be adjusting on these situations and rates as they will be depending on dollars value.
