Command with a default option alias (not value)

Given a command with one option, is there a way to not need to specify that option alias?

From ```app.exe subcommand -a 123``` to ```app.exe subcommand 123``` omitting the ```-a```

The issue describes command-line parsing for app.exe subcommand and asks whether a single option value can omit its -a alias. No files, tests, or entry points are identified; begin by locating the parser and command-option handling, then confirm the desired positional syntax with a focused test.
