🤔 I wonder if it's really necessary / a good idea for consumers to be able to customize this? It inherently means they'll be providing a different experience for sighted vs non-sighted users, because sighted users won't be able to access this text. Visually a loading indicator only indicates that something is loading, so "Loading" should be sufficient always.

Alternatively, we could make this visible by putting it in a tooltip. But that doesn't seem ideal since the loader is not focusable.

Good question, and good point! This mainly stems from https://github.com/github/primer/issues/3465. I believe the idea is, if there's context outside of the input that conveys what is loading then it might be a good idea to add more descriptive text to indicate what is loading so users don't have to navigate outside of it to get that context.

I think this is a more specific use case that won't be used unless necessary, so in most cases having the default "Loading" is okay, which we could make more descriptive 🤔

Cc: @patrickhlauke - curious if you have any additional thoughts here?

If we do keep this prop, I think this (particularly the par about the context outside the input) seems like it would be useful to add to the props documentation. I think what may happen is consumers will see that this prop exists and think that they should fill it out similarly to how they fill out alt text in an image - they'll have good intentions but actually create a less accessible experience.

Yup, that's totally fair @iansan5653! I can add a note on this in the props docs to make sure consumers aren't haphazardly using it!
