I know some are reusing partial views for all kinds of blocks, by simply not using the BlockListItem, BlockGridItem etc base class, but instead passes the content part in, and adding settings in a view data dictionary.
Like so
@await Html.PartialAsync("blocks/" + block.Content.ContentType.Alias, block.Content, new ViewDataDictionary(ViewData){ { "settings", block.Settings }})
The individual block views then use
@inherits UmbracoViewPage<ContentModels.MyBlock>
@{
var settings = ViewData["settings"] as IPublishedElement;
}
