Since Google Cloud DNS does not currently support the record types for DNSSEC, is there any way to begin implementation of DNSSEC using TXT records? If I were using Google Cloud DNS, which I am, and they currently only support record types which include SOA, A, AAAA, CNAME, MX, NS, SPF, SRV, PTR and TXT: am I able to do it while constricted to these record types? Or do I have to wait until support is hard-coded into the service?

I am just wondering because I would really like to ensure absolute integrity for my company so that I only convey realness in it's purity. =D
