Something that I forgot to mention in the other answers similar to this is that the Path().read_text() check only applies if the open() block is a single line, and that line is only used to read the contents of the file. If you are doing other things in that block, no error will be emitted. I agree that open() is pretty ubiquitous, but in certain cases (ie, if I am already using a Path object), using read_text() is a nice one-liner.

read_text() is simpler and _much_ clearer (and thus, Pythonic) when you're doing trivial file operations like reading the contents into a variable. Opening up a whole context manager is still an option when you have to do more complicated stuff to the file.
