Unless they were sold as a supported end-user product, no one in their
right mind outside CDC would build anything other than maybe a one-off with
them, no matter how much better they were.

There were proprietary digital ICs before the standard MECL, RTL, DTL, and
TTL families, too, but they didn't see wide adoption for the same reason.
Engineers need to build products using supported components, not just stuff
thst can be purchased as service spares.
