matchAgeMinDays for delaying delaying inclusion

[betaorbust]

What would you like Renovate to be able to do?

I'd like to be able to have a group of dependencies raised in a change, but only including packages that have had some bake time (for security, stability, etc.) so that auto-merge can be used with them.
I understand stabilityDays is available, but it will hold off automerging a PR until all involved packages are X days old, which is less useful in large groups or with larger timeframes when packages/libraries are constantly being updated.

If you have any ideas on how this should be implemented, please tell us here.

I think this could be implemented with a matchAgeMinDays matcher. It's not maybe a perfect DX because I'm excluding everything and then putting it back in, but it enables this use case of "I want a group of package updates, but only including packages that are older than X days, that can be automerged" and is, I think, a good building block.

{
    "packageRules": [
        {
            "description": "Start by ignoring all minor/patch updates.",
            "matchUpdateTypes": ["minor", "patch"],
            "enabled": false
        },
        {
            "description": "Then opt-in sufficiently aged minor/patch updates as a group.",
            "matchUpdateTypes": ["minor", "patch"],
            "matchAgeMinDays": 5,
            "enabled": true
        },

}

Is this a feature you are interested in implementing yourself?

Maybe

I think this issue is also relevant:

Yes, let's consolidate discussions into #12914 if internalChecksFilter doesn't satisfy. I've converted this one into a Discussion
