And done down to v16, with one logic for HEAD and something simpler for \bind in v16 and v17. Issuing an error if there is a state does not sound like a good idea at this stage because it would suddenly break scripts that expect multiple commands of \bind to prioritize the last one. If that was something only on HEAD, I would have considered that as a serious option, but not with v16 in mind for \bind. -- Michael
