Issue: Username synchronise / Compatibility with Username Change addon for Xenforo

I've noticed when making a username alteration through a third-party Xenforo addon that there are some inconsistencies with the way VaultWiki deals with it. The username change addon is a necessity for my forum for the time due to an anomaly between SMF and Xenforo 'display name' support, although I intend on limiting its use to once every 6-12 months per account to prevent abuse. The addon in question is available here: https://xenforo.com/community/resour...y-siropu.4144/

As this is additional functionality introduced by an addon for Xenforo rather than core functionality I see this as more of a feature request than a bug.

So what do I mean by inconsistent? Here are some examples:

• Article page contributors -> New username is fetched
• Article page last updated by -> Old username is retained
• Article Version History page -> New username is fetched
• Recent Activity Sidebar Widget -> Old username is retained
• Recent Changes special page -> New username is fetched
• Approved wiki edit PM -> New username is fetched
• Alert to subscribed user -> New username is fetched
• Watched Wiki Content contributors -> New username is fetched
• Watched Wiki Content last update -> Old username is retained

Could an Xenforo helper be used more frequently to fetch the current username of a specific user id?

Alternatively, would a deferred task / cron job be a solution? Something like comparing the recorded usernames against a user id in Xenforo and VaultWiki records and synchronising VaultWiki's records if the usernames don't match.

Incidentally the username change addon can apply the username change to custom database table columns, which I think will solve some issues, like usernames in the vw_revision table (solves the old username showing for the recent activity sidebar widget). But this seems like a bit of a hack that involves verifying that vw_revision table structure hasn't changed every time there is an update to VaultWiki.
