Organizations need time to implement post-quantum cryptography (PQC) transition plans methodically — and that applies both to anyone with an IT infrastructure and to anyone building software-defined systems.
If your software isn't capable of using fallback encryption algorithms then your company is already in trouble because it haven't learned shit about security. However, everyone with a lick of sense has made sure multiple encryption algorithms are acceptable in case one becomes a risk. Therefore, you need only need add a PQC encryption algorithm to your software's capabilities (which are now available in most every crypto library thanks to NIST) and wait to remove older algorithms.
The secure communications went through a lot of shit as a result of the Snowden revelations (and subsequent investigation into SSL security) and we are better for it. But as always, those who have failed to learn from the past are doomed to repeat it.
