If, like Stephen says, $progress is part of the base protocol, then there's no capability associated indeed, but I think we should just make up one like `:$progress`, and use change eglot--server-capable-p to be able to respond unequivocally 't' to those special built in capabilities, but only after checking if they're not in the eglot-ignored-server-capabilities list. I think this is more consistent with the other kinds of feature checks we have elsewhere. João
