When updating, the default system admin user's username is reverted to 'system' (if renamed)

This came up here:

Wordpress / discourse integration not connecting

Glad you got it sorted @Jacob_Peebles. As mentioned in the connection video and documentation, the simplest course of action is to just leave the username as the default system. If you choose to change this, you do need to use another username. I’ve added an extra line to the documentation about where to find a user’s username.

Where the username of that account actually matters, as I changed it by hand to something custom. But updates to the forum revert it to the default, is this expected? Now I’ve settled by changing its display name only. But the username change broke the DiscourseConnect SSO publishing (and connection) because it’s a setting in WordPress that did not know that updates to Discourse revert this username.

Yes, this is expected. You can’t permanently change the username of the system user in Discourse (currently).
