It's sold as inert gas for preserving photographic solutions by Tetenal and others with their own brand names. This is first time I hear it not being inert with photographic developers. Possible, though.

The best clear thick plastic bottles are made by Jobo IMHO. I have been able to store developer for up to nearly a year now in them.
I have both clear and brown bottles, including several quart Boston Rounds that I purchased liquid Microdol-X in years ago.
I have no disagreement with your statement, just two questions and a thought.

One small but important advantage to "Amber" is it alerts a person that it not drinkable. Of course, using amber beer bottles or clear soda bottles, this is a real and present danger that is easily avoided.
Labels can fall off or be smudged and not readable so may not be reliable.
One last thought, although not a easy to see as if clear, but holding a amber glass bottle in front of a light bulb, I can see if anything is floating, as least I think I can.
I wonder why Kodak used brown bottles if it was not needed? Would then not of saved a few pennies multiplied by tens of thousands bottles?

Maybe because the retailers wouldn't necessarily store their merchandise in ideal conditions, as opposed to the user, who can at least resort to cardboards?

These are two different situations. However, please note that most all color kits from EK are not in brown bottles, but rather thick plastic, and that liquid developer concentrates such as HC110 are also in clear heavy plastic.
I store my HC-110 in syrup form in the little plastic bottles. I found one, partially used but sealed, which had fallen off a shelf in the darkroom and had to have been there for three years minimum. It was a little darker than the new, but tested fine. I used it up and haven't worried about HC-110 keeping any more!
Swing by your local chemistry lab and ask they if they have any old acid bottles - sulfuric, nitric, hydrochloric, it doesn't matter which, and see if they will give you some. They are clear, heavy glass with a chemical resistant cap and they typically have a clear plastic coating on them so that if they get dropped, they will not loose all the liquid in them. (That is, as long as they don't get the neck broken on them...)
They are usually in the 4 Liter size.
For up from the ashes, up from the ashes, grow the roses of success!
Consider the Caps --- Liters not Quarts
Likely you should have the Polycone or Polyseal caps.

Also the bottles are some fraction of a liter save for
the 1 ounce which is over sized. A 2 ounce is 62.5 ml,
a 4 ounce is 125 ml and on up. Boston Rounds are much
in use. The exact hue of the ambers may vary slightly
from one batch to another and from one or another
