First, I must inform you that no photographic processing solution is overly sensitive to light. Dichromates and some staining developers are sensitive to UV radiation.
However, I would also like to point out that in a DARKroom it is seldom very light and rarely has any UV. Even if you store the chemistry in the kitchen or bathroom, how bright is it? How much UV?
This is the most frequently quoted non-problem. At Kodak, we used a lot of clear glass bottles for chemical storage, and with plain cork stoppers.

I personally find it hard to squeeze out the excess air from an amber glass bottle. Maybe it is just something about me.
I guess you lost your marbles?
This is an interesting discussion.
In over 60 years of photography, starting at about 8 - 12 years of age, I have never mixed up process chemistry regardless of labeling or no labeling. I have never had this sort of problem. I label nontheless, but have never confused chemistry.
I just wonder how much attention you guys pay to chemistry and whether you use different type bottles for each chemical? I do.

I'm probably just being analog-retentive.
On the subject of glass vs plastic bottles, glass has a couple of advantages (that I can think of at least) over plastic. Plastic bottles "breath", glass doesn't (assuming a good seal at the opening). How significant of a factor this is, I don't know. Developers would be more prone to oxidation than most other chemicals. Second, you can mechanically remove the excess air from a glass bottle and it won't collapse.
Who would have guessed that there would be so much interest in such a simple concept as labels
Charles, let the Formulary know. The original bottle was probably defective.
