As a developer, using Roblox API is more convenient than having to maintain my own codebase using raw links for thumbnail content ID. With the Release Notes for 439, there is a pending feature for circular thumbnails to the rbxthumb ContentId format. This feature should be used with the current Roblox API Players:GetUserThumbnailAsync() (documentation). This API also returns when the thumbnail is ready, while the direct link does not.
If this API was updated to use the new circular design, it would keep my codebase clean and more convenient to use by referring to a single API that maintains all the Player Thumbnail links.
