Using ifindex instead of string matching the interface name in -i and -o would be a serious problem as it changes the semantics. 1) Now you can match a non existing interface. This is certainly used. I.e. with vlan interfaces, ppp etc. 2) Now your rule will match an interface even if the ifindex of the interface changes. This is used (i.e. you activate a backup interface and rename it, build new bridges etc.). If one wants to use the ifindex instead of a string match on the name one should explicitly request that (i.e. by using "-i =eth0" or something like that).
