but writethrough makes sense for slow devices

And also for all removable devices, because with them it is common you want to flush all pending writes and unmount.

*all* removable devices?? What you describe is common for USB key, sure, but what about USB HDD?
I'm sure that some users have such an HDD plugged in all the time and they would object to the performance degradation..

I am myself one of those, finding that the easiest way to expand storage on my old home PC. But I think that is still exceptional, and could be solved by passing a parameter when mounting (in fstab? I have those drives mounted the traditional way, instead of hot-plugging), or later via some tuning command.
