However, I do think it would be a good idea to [optionally] add a

hopefully not by too much since the segments file is small.
To increase crash resilience, one would want to sync all the segment
files *before* writing the new segments file. Of course it's not
always easy to ensure data is actually on stable storage:

Ahh yes you're right.
And indeed even with sync. writing of all the segments files, the hard
drives themselves often cache writes by default these days.
