Hi. First, sorry if this wasn't the best way to contact you, or if you aren't the best person to contact - I wasn't sure how to contact the team working on WVUI and since you are one of the developers I figured I could ask you or you could tell me who to ask.
In the GlobalWatchlist extension (Extension:GlobalWatchlist) there is currently a basic Vue version of the display, to be used instead of the one build on jQuery/OOUI. The Vue version is not enabled for production yet, and one of the reasons is because we don't have a good loading component (the indeterminate progress bar that is shown while the entries are being fetched). In the OOUI version this is a OO.ui.ProgressBarWidget[1]. I was wondering if there were plans to add a similar component to the WVUI library? There is already such a component in the "Wikibase Vue components" library[2] but that library is not used in MediaWiki core or made available to extensions as far as I know.
If there are no such plans already, would the WVUI team consider it? If not, I guess GlobalWatchlist can always just create its own (perhaps based on the Wikibase version) but since I think this type of component might get reused elsewhere I would think it makes more sense to add it to WVUI (in phab:T272885 where existing components in various extensions and libraries were identified, ContentTranslation already has a similar progress bar).
