There will always be need for some analog radio and equipment. Aside from certain immunities they can entail, certain uses (notably critical MGM usage) depends on analogue because SSB, RTTY (and other FSK modes) and CW still functions better in being resolvable by human and machine under extremes which render pure digital modes unresolvable - under such conditions, about the only pure digital modes which survive such conditions (at a ridiculously and and diabolically low transfer rate, but with solid error correction will eventually complete the send) are packet modes, pure FSK RTTY (SVCF type) TOR and CW.
Most resistant LEP (long earth path) modes are digital encapsulated in an analog transmission mode. Often it’s an analog mode FSK basis.
So yes, analog can and will survive until totally superceded in all aspects and circumstances and we’re way feet deep into toddler steps as far as navigation of that ideal goes.
Just look at Moon bounce communication, which as close as you’ll get to interplanetary distance long path communication at present, that demonstrates why technically that pure digital modes and interception of super weak and phase and Doppler shifting signals are very much something that favours digital over analog over pure digital.
In fact, even the whole space program activity across the world relies on having an analog fallback at the very least even in the era of wide satellite networking and backbone subnets.
But I guess most LMR people wouldn’t know those factors ever existed let alone were a factor to what survives in radio.
Bottom line, if people are prepared to use a so-called redundant form of radio, legit or otherwise, it’s survived by default and whilst it survives in some regular and scheduled use, it never really got superceded or replaced and stands a very low probability of dieing a persistent permanent death.
The only radio transmission mode that truly died was (telegraphic) spark gap transmission, and even then unofficially not entirely because you can technically make an emergency beacon literally using the spark-gap nature of a piezoelectric lighter, which modified appropriately could actually save your life in an earthquake when buried/trapped.
But I guess I live in a very diverse world and window of perception of radio.
