I'm trying to think of an example of a standard where the fixed sized index got full but re-use was a viable long term solution instead of either extension or complete replacement. It seems if that point gets hit the amount of effort to reuse isn't worth the short amount of time it gains. In IPv4 for example we reached the second level of NAT before anyone even tried to start using 0/8 which was set aside simply to not be used not even assigned and forgotten.
