“I would like it if the iD 'adjust imagery tool' button were more visible.”
I agree on this, it needs to be more prominent and ideally iD would make it’s users align the imagery before letting them edit.
Dose iD’s tutorial/guide teach about offsets?
If not I think it should as they are very important when editing from imagery and I imagine most iD mappers do this.

So, I followed the links below and added an offset. But this simply
isn't a viable solution to the problem because it only works for JOSM
and not iD.
I managed to convince one mapper to type in the offset manually in iD
every time, but that is a horrible thing to ask new mappers to do,
very offputting. And now I can see Amazon mappers using an iD variant
that doesn't have the offset and moving all the roads as a result:

This is going to keep happening so long as OSM has multiple image
sources and multiple editors. Frankly I'm amazed that this isn't a
solved problem.
Imagery isn't one image. There are carefully blended seams that often include jumps if you look closely. There is also no guarantee that distortion to "flatten" hills etc. We also tend to receive no metadata about where the seams are, or how they were distorted. It is not an easy problem to solve.
Having done some mapping across the country recently, it seems like
Bing is offset to the previous best imagery across the country, but by
varying amounts. Is there really no solution that can be applied to
the source Bing layer? Or should we all just accept Bing as golden?
I think we tend to accept OS's StreetView as the best source for position.
Having added thousands of buildings and fixed roads to align to the
previous best imagery, I don't have a good solution to the problem,
and it is demotivating to think that others are going to come along
and move individual roads/buildings to align without considering the
bigger picture.
Poorly considered hit and run mapping will happen regardless of the imagery.
At least talk-gb doesn't have to deal with those with "humanitarian" inspiration. These can be prolific and sometime give the impression they are too busy "helping people" to read even basic instructions. (Especially the ones who go off piste)
The only solution I can think of is to move all nodes in the area I've
worked on to match the new Bing (ie a mass edit). Any other
suggestions?
Readjusting every time a source updates is not a good solution. It assumes there is one "authoritative" source and would become and endless task.
I would like it if the iD 'adjust imagery tool' button were more visible.
