feat: detect flag extinctions

[jazanne]

For each removed flag, we will check if there are any other references remaining i the code! This will make cleanup much easier

I think this is great! Although, I'm not sure the skull is very clear. Maybe we need another column that says "all references removed" or something like this.

confirming that if there are no remaining references then the alias found colmn should be empty, right?

@UPatel12 No, the alias found column is showing that those aliases were found and removed - will tag you in a comment to make it more clear

[jazanne]

@UPatel12 this alias of beta-ui is what was removed, so we try to let people know

I'm leaning toward option 2 (without the check mark) out of the two options. The skull & check mark are a little confusing.

I like Kerrie's idea of adding a new column for all references that have been removed.

2 options:

• Column can be True or False. Are all references removed or not.
• Column can be a count of the references found/remaining. For extinct flags, the colmn entry would be zero.

Column can be a count of the references found/remaining. For extinct flags, the colmn entry would be zero.

we don't scan for all flags in repo so we can't do count

I really think a boolean column w/true or false will not be visually compelling enough

Name	Key	Aliases found	All references removed
Show widgets	show-widgets	showWidgets	false
Beta UI	beta-ui	betaUi, beta_ui	true

Maybe the column is something like "all references removed" and then has a checkmark

Name	Key	Aliases found	All references removed
Show widgets	show-widgets	showWidgets
Beta UI	beta-ui	betaUi, beta_ui	✅

I want to make sure we're presenting all the info in a way that's really easy to grasp from a quick scan.

Proposal for change to 4 columns...

sad, this was wrong before
