the obvious problem is when you don’t have a “known good state” to revert to – it’s all too easy to get carried away when creating a new configuration to get muddled up before the stage of feeling it’s time to save an endpoint. At least knowing that an instance can’t be properly removed should ring a bell that perhaps a save should be in order before creating possibly superfluous new ones.
For me, it’s not really an issue any more as I have satisfactory playback templates to revert back to.
