I hope your customers are happy with connectivity to "most major networks".
Do you have data on how much visibility you have of the v6 internet? It
should be moderately easy to figure out how many ASNs you have connectivity
to, with and without a /32 supernet announcement. Pingable v6 addresses
can often be determined by using other tools (e.g. traceroute, irrdb
"pingable:" fields, etc). All you need is one per ASN - that's only 5700
