If this has already been taken into consideration, I apologize.
I think it would be very beneficial to add additional website recognition and icons for links on profiles. Maybe even take user requests for which ones. For example, despite Tumblr not being as popular as it once was, there are people like myself who still use it and would appreciate some consistency on our user pages.
It also seems like links such as specific YouTube videos aren’t recognized as YouTube, nor are links to Steam profiles recognized as Steam.
