My issue with argparse isn't that it's not global, it's that you have to create sub-parsers for multiple commands, and then add arguments to those subparsers. Those parsers are all typically defined in a central location, but copying arguments between those parsers as I define new commands can get them jumbled up because the sub-parser comes along with the argument:
sub1 = [create subparser]
sub1.add_argument('-x')
sub2 = [create subparser]
Typer completely eliminates this potential bug, because the arguments are defined as type annotations in the sub-command function itself.

Gee if only there was a way to reuse logic within a program.

So you duplicate logic in your type definitions instead of as instructions. Whatever makes you happy i guess.
> Passing arguments to functions is thread-safe, but that soon becomes tedious when there’s more than a few or when they need to pass down through several layers of calls before reaching the point they should affect. Introducing a new setting to existing code is often easier with a parameter object than adding arguments.
But also, if you really wanted to, you could set the argsparse object to a global variable and then import it everywhere else. So that is not a limitation.
