Those raised things on the sides are not phasers. The two ends are the phasers and there is nothing around them. The gold rectangles are in isolation. And while in Trek timeline they are not close, in production the Ent D isn't that remote and its RCS have no lit portion. Same with Ent C, Voyager, and NX-01. Also, there are no obvious RCS on the TOS enterprise. So the lighted area is not a requirement for RCS. Nothing about the marks indicates phaser other than they are on the side of a double ended mega-phaser tube (with the phaser emitter at either end).
Here is a close-up of those gold rectangles. Do you see any thruster dots on the corners of the rectangles?

And below is a close-up of the saucer rcs. Notice the thruster dots on the corners?

Also if you pay attention to the origin point and angle of the phaser pulses you can tell they are not coming from the front ends. The first phaser volley (above) intersects with where the gold rectangles would be. The second phaser volley intersects a little higher with the blue side piece that look suspiciously like phaser ball turrets.

I'm not sure how you can argue that those gold rectangles on the rollbar are RCS thrusters when they lack the thruster part.
