Again, what is the value of the average passenger knowing that their line is classified as a "rapid transit line"? Do you think they'll turn around and say "no, thank you" if they see that it isn't classified as such?Yes.
Point being that people shouldn't have to be adaptable or have puzzles they need to figure out. It should be easy and intuitive for people who aren't familiar with the system. A clear and consistent sign that tells people that it's a rapid transit station is the most basic of useful information, which is why most cities use a simple M or something similar. Our way of using a T for some rapid transit lines (but also bus stops and GO train stations) and a TTC logo for other rapid transit lines (but also bus and streetcar stops) is needlessly unclear.
These obelisks are ridiculous and of dubious value, but the fact that they don't call out the form of transport is far and away at the very bottom of the list of concerns.
