Cherenkov radiation is emitted whenever charged particles pass through matter with a velocity exceeding the velocity of light in the medium.
The charged particles polarize the molecules, which then turn back rapidly to their ground state, emitting prompt radiation.
And you wrote, "Frank and Tamm developed the theory behind Cherenkov radiation assuming
(my bolding) a point charge moving with a uniform velocity.
Now, I can imagine that for an interval of time a charged particle can move though a matter medium at a constant velocity, but I can't imagine that the entire path of a charged particle through a matter medium will be at constant velocity (unaccelerated).
So, I will concede that Cherenkov radiation can occur as a charged particle moves at uniform >c velocity through a matter medium on its way to decelerated < c velocity.
I trust you will concede that, although you stated "A charge moving with a constant velocity can radiate, if they velocity is greater than that of light in the medium" that it is actually the electrons of the excited medium that radiate and not the charged particle moving at constant velocity.
