Obsidian has the philosophy that the filesystem is the source of all truth, and it's showing directly the filesystem without any obvious layer in-between. The reason is, that you should be able to read your data with any other app and have the same amount of data accessible. So from their POV, there is not really any place to store the information for the sorting. Adding it to the filename, would annoy the people, so It's up to you to choose your own plugin allowing this.
Also, with the new bases-features, you can easily create your own sorting with a table, or whichever view you prefer.
