So do I, but I with there was a new one TCP_RTTDELAY. It would take a byte that would be what 128th of RTT you want to use for Nagle instead of one RTT or full* buffer. 0 would be the default, behaving as you and I prefer.

* "Given the vast amount of work a modern server can do in even a few hundred microseconds, delaying sending data for even one RTT isn’t clearly a win."

I don't think that's such an issue anymore either, given that the server produces so much data it fills the output buffer quickly anyway, the data is then immediately sent before the delay runs its course.
