Suggested change

	One major missing piece for full `kubectl`-style argument handling is support
	One major missing piece for complete `kubectl` style argument handling is the support

[skitt]

I’ve rephrased it:

It doesn’t set up a `--kubeconfig` flag,
which you might want to do to align with `kubectl`;
you’ll see how to do this [later on](#bind-the-flags).

[Ritikaa96]

Thats good. Maybe you can rewrite the last one as you'll see how to do this in [bind-the-flags] section later in this blog Current one is ok as well. It just add some more direct reference here.

[sftim]

Here's one way to reconcile github.com/spf13/pflag with the jargon from the wider world of IT.

Suggested change

	// Overrides and flag setup
	// Overrides and flag (command line option) setup

[skitt]

Or “command line argument” to avoid yet another term 😉.

Hi. We're now looking at publication in September 2024.

[sftim]

How about publication on the 26th? Please aim for that.

[sftim]

Thanks! Here's some feedback that I think would get this good to merge.

[sftim]

OK! This needs a tech review next. Either SIG CLI or SIG API Machinery; take your pick.

I vote for SIG CLI.

[skitt]

@sftim is it up to me to request a technical review from SIG CLI?

[sftim]

Hi. The blog team is short on capacity, so reviews are taking a long time. How about we aim for publication on the 2nd of December?

As per above discussion, the PR is still waiting for reviews so removing the tag

Sorry about the wait on this.

Would you still like to publish it?
