I've been thinking about this for quite some time, and don't you think that the data results should last longer than 3 months? I mean, why not just stick to 6 months instead of 3 as it just feels drastically too short. You don't have to agree with me on this if you don't want to. It's just a suggestion, not a requirement.

This is a perennial question. I believe the WMF considers it a breach of personal data policy to permit searching the records further back. Technically it is quite possible to extend the period and it would help combat the fiercly growing abuse of Wikipedia - at least on en.Wiki - for commercial purposes. ~~~~
That could be true either way.
You can change that by setting $wgCUDMaxAge to a longer period.
If you want to change that on WMF wikis, the request should be discussed and approved first, but anyway this talk page is not the place to take this discussion. Maybe try a bugreport?
Exactly. The way MediaWiki is used on WMF projects is driven by the WMF and it's unlikely they will approve any changes to their policy even if asked time and time again by a majority RfC from their volunteer communities. Hence making a request at Phab would be a waste of time. The simple $wgCUDMaxAge setting is free for anyone to use who is using MediaWiki for other purposes.
Oh yeah. Although I'm not a Steward on any of these wikis.
I believe we have adequately explained the situation with the use of CU on WMF and non-WMF websites powered by MediaWiki. ~~~~
