Updated the description to reflect that the ExternalGuidance stream should be decommissioned.

(Also, sorry, Yuvi—I removed your username from the description, so you should be safe from this task now 😊)

Edited task to only include schemas we don't yet know what to do with.

@MMiller_WMF do you know if we can decom the GuidedTour* schemas? See also https://phabricator.wikimedia.org/T288416#7319640

From what I can see, support for producing Schema:EditConflict was added by personal request in 2014 and I don't think it was ever consumed. Data has not been sanitized, so there's no historical record to preserve. Data collected is redundant with TwoColConflictConflict, which is actively used.

I recommend dropping the event and all data.

If there is somehow a historical record of this table going back to 2014, please preserve, that would be valuable.

I'd like to see some discussion about the $wgPingback defaults. According to our documentation, the pingback checkbox is opt-out during installation. But this is a rather invasive setting, as far as I know it's the only thing in MediaWiki to "call home", and it reveals IP address, operating system, PHP and MediaWiki version. The data could be abused in many ways including as part of an attack. I would personally like to see this become opt-in, or at least see that there's already some kind of consensus that we—"we" being problematic here because that group likely doesn't include the new sysadmins sending the pingback—are okay with the current behavior.

After updating the audit spreadsheet, I removed more of the schemas we know what to do with from this task description.

Schema	Migrate or Decom?	Owners?	codesearch results?
UserFeedback		SSethi (WMF)	yes

AIUI a gadget produced UserFeedback events and that gadget was undeployed (per T248892#6547896 and T248892#6557192). The Global Search tool yields no results for UserFeedback in the Gadget, Gadget_talk, Gadget_definition, and Gadget_definition_talk namespaces.

@srishakatux, @bd808: Do you know if the gadget is deployed anywhere else? If not, I'll submit a patch to remove the UserFeedback EventLoggingSchemas entry.

It is not anywhere else, so +1 to removing. Thanks for the ping.

@Ottomata
The AdvancedSearchRequest data stream can be decommissioned. Sorry for the lag, this somehow slipped through.
