As a Roblox developer this would be useful because a significant amount of designers who produce accessories and clothing use links to searches as a way to present their items on the site in places like item descriptions, group walls and social media to keep users updated with the most recent items by using a link that shows the Recently Updated sort. I discovered this was a thing when I clicked a broken link in a user’s description because they’re unaware that it broke after they changed their username.
Given that usernames cannot be used by more than one user, this seems like it could be reasonable and possibly expected behaviour, especially considering that the current behaviour confusingly returns the Relevance page.
Example:
Current username search, returning all of their items:
https://www.roblox.com/catalog/?Category=13&Subcategory=40&CreatorName=im50feettall
Previous username search, returning the relevance view:
https://www.roblox.com/catalog/?Category=13&Subcategory=40&CreatorName=kegstrude
