def do_delete_user_preserving_messages(user_profile: UserProfile) -> None:
    """This is a version of do_delete_user which does not delete messages
    that the user was a participant in, and thus is less potentially
    disruptive to other users.

    The code is a bit tricky, because we want to, at some point, call
    user_profile.delete() to trigger cascading deletions of related
    models - but we need to avoid the cascades deleting all messages
    sent by the user to avoid messing up history of public stream
    conversations that they may have participated in.

    Not recommended for general use due to the following quirks:
    * Does not live-update other clients via `send_event_on_commit`
      about the user's new name, email, or other attributes.
    * Not guaranteed to clear caches containing the deleted users. The
      temporary user may be visible briefly in caches due to the
      UserProfile model's post_save hook.
    * Deletes `acting_user`/`modified_user` entries in RealmAuditLog,
      potentially leading to corruption in audit tables if the user had,
      for example, changed organization-level settings previously.
    * May violate invariants like deleting the only subscriber to a
      stream/group or the last owner in a realm.
    * Will remove MutedUser records for other users who might have
      muted this user.
    * Will destroy Attachment/ArchivedAttachment records for files
      uploaded by the user, making them inaccessible.
    * Will destroy ArchivedMessage records associated with the user,
      making them impossible to restore from backups.
    * Will destroy Reaction/Submessage objects for reactions/poll
      votes done by the user.

    Most of these issues are not relevant for the common case that the
    user being deleted hasn't used Zulip extensively.

    It is possible a different algorithm that worked via overwriting
    the UserProfile's values with RealmUserDefault values, as well as
    a targeted set of deletions of cascading models (`Subscription`,
    `UserMessage`, `CustomProfileFieldValue`, etc.) would be a cleaner
    path to a high quality system.

    Other lesser quirks to be aware of:
    * The deleted user will disappear from all "Read receipts"
      displays, as all UserMessage rows will have been deleted.
    * Raw Markdown syntax mentioning the user still contain their
      original name (though modern clients will look up the user via
      `data-user-id` and display the current name). This is hard to
      change, and not important, since nothing prevents other users from
      just typing the user's name in their own messages.
    * Consumes a user ID sequence number, resulting in gaps in the
      space of user IDs that contain actual users.
