It is a big job to update and verify the FMGS/ECAM data bases, and not one to be taken lightly. A navigation download takes 20 mins or more involving floppy discs on older A320 family, and it can fail, requiring the process to be repeated. Not ideal during a turnaround - having engineers in the cockpit and unable to access the FMGS for that length of time. (no disrespect to engineers).
The new data base has to be checked and cross checked for errors by the approved provider, so is not something you would want to do or have to afford for every change.
OEBs are supposed to be temporary until a permanent fix is worked out for engineering to implement.
