Why was the dted() function hardcoded to read from lowest (0) to highest (3) level?

This is more a question to the relevant Mapping Toolbox developers, and probably isn't the most appropriate area or way to ask.

Inside of dted.m, line 170, the code attempts to search for a matching dted file from level 0, 1, 2, and finally 3.

This seems like an odd choice to hardcode 0:3 without providing an additional key/value parameter to specify search order (i.e., highest to lowest) instead. The current implementation makes passing a folder path to dted() rather useless, as I currently have to resort to manually checking if higher levels exists first and individually read each file with a corresponding dted() call. If instead we were able to change the search order (i.e. 3:-1:0), calling dted() with a folder would guarantee that the highest level dted files are used if available.

For background, I am working on an application where all level 0 files are available, but they should only be treated as a backup option if higher levels are not available first. Having the highest resolutions (if available) is absolutely preferred over level 0. I imagine there are other MATLAB users that would have similar requirements.
