File-transfer is a bad example. A good example would me multiplexed REQ-RES protocol. There is no reason for Message #2 to wait on message #1.

This issue, however, is so overblown by the author. It's not that often earlier packages delayed and new packages arrive faster and when that happens often you problem is usually much greater than server waiting for 101-200 before sending 201-300 to application...

To me the most annoying part of TCP are:

- Slow Start - Single channel - Single Mode

Everyone life would be so much better if within a single established connection you could open multiple channels in multiple modes like framed vs stream. Each channel could have its own order with congestion control overseeing entire bunch of channels.

You can build something similar on top TCP today, but it's not the same. Best part of TCP is that it's a standard available everywhere without conflicting implementations.
