Do you mean the other way around, 25Mbps Down and 10 Mbps up?
It is nice to have, especially when it doesn't cost much. That is why I am perfectly OK with PON rather than dedicated fibre. You only need the 1 or 10Gbps speed for may be a 10 min window per month.
I do think 25Mbps on a house hold bases is quite low. On a 5Mbps Video file I want the first 10 second buffer, 50Mbps done instantly. While I am loading multiple page in the background. Multiply that with a few more user in family. It is perfectly useable a you said, if you dont mind waiting.
Otherwise I think 50 - 100Mbps per person is generally the point we see law of diminishing returns.
