yes; you can be semi-blocked from sending by the range of the lowest unacked packet you have outstanding.

I say semi-blocked (as opposed to say, deadlocked) because you can just move to the bigger packet number space and essentially declare the older uacked ones presumed-lost. They'll fail decryption at the receiver when given the 'wrong' packet number.

8 bit numbers  aren't especially useful.. perhaps banning them as footguns would be a practical step to help quality of implementations.
