old host macros in database

[samarit]

I found that database table 'hostmacro' contains host macros for already deleted hosts. If hosts in zabbix are often deleted and added, 'hostmacro' contains some garbage data (old macros). I think procedure must be:
when host has deleted, all macros for this host also must be deleted from database. Is not right?
