Access to underlying click capabilities in the vendored click world

First Check

• I added a very descriptive title here.
• I used the GitHub search to find a similar question and didn't find it.
• I searched the documentation, with the integrated search.
• I already searched in Google "How to X" and didn't find any information.
• I already read and followed all the tutorials in the docs and didn't find an answer.

Example Code

# how should I do this?

class LocatorParser(click.ParamType):
    # weirdly the name field is the thing that gets printed in the help message as the type
    name = "text"

    def convert(self, value: str, param, ctx) -> Locator:
        # my custom conversion logic goes here
        return Locator("blah")


## or, how about this?
from click import get_current_context

def my_method_that_might_result_in_needing_to_reinvoke():
    if my_condition_to_reinvoke:
        ctx = get_current_context()
        ctx.invoke(ctx.command, *ctx.args, **ctx.params)

Description

What is the recommended approach for accessing click internals now that it's bundled in typer? Is there a canonical way to do things like override param types?

Hi!

We strongly recommend against using any functions/methods from the typer/_click module (in 0.26.0+) directly, as these will be subject to change in the near future. There's a high chance we will refactor the Context stuff, too.

We want to carefully reconsider which Click functionality we want to keep in the future. When it's things we want to keep, we'll expand the Typer codebase and documentation to cover it clearly. When it's things we don't want to keep, we're likely to remove them from the vendored code.

If there are Click capabilities not currently covered by Typer's public API, I suggest you create a separate Discussion thread for each such piece of functionality. Explain what exactly you'd want and why, and what it could look like. We'll then discuss whether this is something we'll want to support in the future, and we can take it from there.
