Suggested change

	The `relabel_rules` argument can make use of the `rules` export value from a
	[prometheus.relabel][] component to apply one or more relabeling rules to metric data points
	before they're forwarded to the list of receivers in `forward_to`.
	The `relabel_rules` argument uses the `rules` export value from a [prometheus.relabel][] component to apply one or more relabeling rules to your metric data points. The metric data points are relabeled and forwarded to the list of receivers in `forward_to`.

A small rework to make the information active instead of passive. Is it still technically accurate with these changes?

If this is correct, this change shoudl be applied to teh other cases here in each of the following doc topics.

Hey @hainenber, sorry for leaving you hanging for so long here 😞 Unfortunately I'm not sure about the proposed functionality in grafana/alloy#192, so I'm holding off on reviewing this from an implementation standpoint.

We've recently introduced a new proposal review process that will help make it easier to understand when things still need discussion and when they're ready for work.

I'm going to mark grafana/alloy#192 as a proposal so it can be discussed and we can reach consensus on whether this is something we want to do.

[hainenber]

No worries! It's always good having more opinions to a proposed addition. More code means more debts after all 🤤

[rfratto]

Feel free to chime in for any proposal you think we should do, we want to welcome opinions from everyone and not just maintainers :)
