A daemon to respond to selected ICMP requests would be simple to write.
I don't recall the RFC making any low latency requirements for ICMP either.

I'm not sure I see any great benefit from it though - the kernel still has
to understand ICMP (for port unreachables etc), so all it achieves is dropping
a few bits of ICMP response code from the kernel. ICMP filtering is doable with
ipchains etc anyway. Debian don't ship heavily patched kernels, so unless this
happened upstream it's unlikely to appear in Debian.
