Honestly, I do not mind. The only thing that should be held up when it comes to block size is that the blockchain remains small enough for everyone to store it on their personal computer or raspberry pi.

IMO the maximum would be quadrupling the current block size - that would still be manageable since the difference in price between 1tb HDD and 4tb HDD is small. After that the prices rise quickly.

Keeping it at the current size would be the more elegant way to go forward tho.
