Because they went for stealth, not speed?

The SR-71 had the fabulous J-58. It main feature was the bypass tubes to feed the afterburner.
Does anyone know why none of the engine manuf never carried on with that technology?
Probably because there are no need at the moment

In recent times GE had the YF120 developed for the ATF, it was used as a base for the RTA-1 which was meant to work like a ramjet at high speeds and reach M = 4.1.
Interestingly this is roughly the same speed touted for the speculative MiG-41, so it is quite possible that such concepts are being entertained in Russia too.
