small question about constantly accelerating charges

[gneual]

I've seen the question of whether a constantly accelerating charged particle emits EM radiation posed in the context of gravitational acceleration and apparently is an open question, and answers bringing up the "equivalence principle", such as in the following threads:

https://physics.stackexchange.com/q...accelerating-in-a-gravitational-field-radiate
https://physics.stackexchange.com/q...ing-charged-particle-emit-em-radiation-or-not
https://physics.stackexchange.com/questions/89093/do-accelerated-charges-radiate-or-not

But for other sources of uniform acceleration on a charged particle, it is not controversial right? Such as when the Lorentz electric force causes a particle in a uniform electric field to undergo uniform linear acceleration; this indeed emits electromagnetic radiation on a continuous spectrum according to Larmor's formula and is not a controversy right?

The question is not particularly controversial if the person asking the question clarifies one specific point that is usually neglected:

How do you intend to measure the radiation? Specifically, are you measuring it with an inertial antenna or a co-accelerating antenna?

I see, so whether it is controversial depends on how it is interpreted, specifically the inertial reference frame? So the cause of the acceleration -- such as electric part of the Lorentz force, or gravity, is irrelevant here?

Not the reference frame. The proper acceleration of the antenna is what matters. Is the antenna inertia or co-accelerating.

Yes
