Orbited plugin may not work at all anymore, I had no means to try it.
But there's a check whether 'LACONICA' is defined there, which is a
very unlikely thing in the future. So far only tests and scripts have

This provides initial infrastructure for decoupling display names from internal canonical names, but continues to have us storing and using the canonical forms.
It should be/become possible to provide mixed-case and underscore-containing names in links, @-mention, !-group, etc, but we don't store those alternate forms generally.
