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).

It puzzled me so much when my mail receiver didn’t work anymore randomly.
I could trace the error back to my last rebuild, and noticed the API username I set in the config file didn’t exist anymore on my forum.

I had indeed changed the system account’s username, and it was reverted after the rebuild.

That’s how I learned we couldn’t, in fact, change this account username.

I’d prefer that we just couldn’t change it at all in the interface.
