Ok, makes sense.
What about the frequency of releases?
There only was a single release of the companions until now.

No, not at all.
We only want to guarantee, that all logfiles are rotated when the files are
collected for analysis purposes.
Since there can be extra logfiles configured for messages with very log frequency,
it simply is not possible to defer logrotate until the next log message.

I will prepare a patch and open an enhancement bugzilla.
