What is the point of adding something to make those non-routable uses
routable, if the protocol is already supposed to be routable?

What is the point of handing someone a microphone in conference so that others further away can hear them?  Does handing them a microphone change what they are saying?
The purpose of DHCP relay / helper agents is to take the DHCP packet which is using non-routable source (0.0.0.0) and destination (255.255.255.255.) and send send / proxy them to the DHCP server using routable source (relay) and destination (remote DHCP server).
The only other modification that I'm aware that a DHCP relay / helper does is add an additional field to identify the the relay / helper and the source client's MAC address in the outgoing DHCP packet.  The rest of the contents of the DHCP packet is substantively unmodified.
What's more is that the DHCP packet format (the unit the protocol speaks in) is the same for both use cases, client <-> relay as well as relay <-> server.
If a child picks up a basket of toys but can't reach the shelf, does the basket of toys change when an adult takes the basket and places it on the shelf for the child?  Does adding the child's name to the front of the basket alter the basket contents?  No, and no, tt is still the same basket of toys.
