HNDL can be worth it without the "threat" of quantum computing; for instance we see currently a lot of interest in AI-assisted math, and maybe it could lead to a breakthrough that affect crypto algorithms that are currently considered safe.
Therefore it seems weird to use QC as a benchmark. Rather, if your communications being decrypted in the future is unacceptable, then the logical conclusion is that you must not transmit it in such a way that a third party can intercept it.
Admittedly, it is inconvenient or even impractical, so people do accept the risk anyway without admitting it. They are sweeping the issue under the carpet of supposedly QC-proof crypto - because new quantum algorithms can be discovered too.
