what do you think about cleaning the routing table on mask change?

I think it would be far easier and more correct to not allow
just the mask change (which is never really needed).

$ ifconfig tap0 10.1.1.0/24
$ netstat -nr | grep tap0
10.1.1.0/24 link#6 UC 0 0 tap0
$ ifconfig tap0 10.1.1.0/26
$ netstat -nr | grep tap0
10.1.1.0/26 link#6 UC 0 0 tap0
