Traffic signs are punctual items, their supposed effect (our interpretation what they imply for which way) is already mapped with established tags on the way. It is more accurate and more useful (for finding problems and inconsistencies) to have the signs mapped as nodes. Let me give you an example: I do find it helpful to map maxspeed signs on nodes (doing it at the side of the highway because this implies the direction), because it helps to verify and maintain the speed limit data on the highway. If these were replaced by tags on the highway it would be less useful, because they would merely repeat the information that maxspeed already gives, and you won’t have neither the confirmation of repeated max speed signs nor would you know until where a later discovered sign with a different maxspeed is “at most” valid. Every time you discover a new sign, with the tag on the way method you start again “from scratch”. Adding traffic sign ids to ways makes only sense if you mistrust the osm tags, e.g. because there aren’t the exact tags you would need to describe the effect of a sign. My suggestion would be to improve/amend the system of human readable tags in this case, so that they fulfill your local requirements. I do recognize there can be some usefulness in both information (actual signs and their position=nodes, and the actual signs that led to certain tags being applied on an object (=ways)). I am not sure it is a good idea to use the same tags for it.
