Hm, I think it should be under flag, what do you think?

Should it be a flag? Receiver sets this option to true by default. Is there any use case that people want to set it to false?

It is an option in Prometheus, plus false by default, so I would stick to the same here. You are right for the receiver - we might want the option as well.

I have added a flag for rule and receive. Should I add the changelog?

Definitely worth mentioning in changelog if the default has changed

WAL compression is intended to become the default in Prometheus, we just can't do it in Prometheus yet as that would be too breaking of a change. I personally think we should just always have WAL compression enabled, the CPU footprint of receive is so tiny it's the right trade-off in my opinion.

tl;dr I think we should leave things as they are in this regard.

Should we make it true by default then?

I'm not sure this should be configurable at all, but yes if this config option exists then it should definitely be true by default.
