Why are issues assigned to only one user on close?

Hi 👋,
I'm wondering about the motivation of assigning an issue to only one user on issue.close().
I'd rather expect the close function to not interfer with assignees.

As a close is effectively an issue update, the currently assigned users should be used so no re-assign happens on close.

It predates the ability to have multiple assignees likely if you do a blame. In other words, when support for multiple assignees was added it was missed. Happy to review and merge a PR fixing it
