a solution to this should be done generically, we already have
CONFIG_HARDCODED_TABLES to switch between fixed and runtime inited static
tables, an additional variant for heap allocated (and at exit() deallocated)
tables could be added

Its IMHO bad to awnser the same question (that is about static tables)
