That’s a good thing. Discord is chugging its way through the last half of the Web 2.0 service to social media pipeline. It’s a VC-funded multimedia enterprise extended around a novel technology core optimized for its original service offering, real-time voice/text. Nobody is immune to bloat, but because Matrix is a protocol standard, not an app, users have the option of sticking with minimal clients and servers that won’t (necessarily) get destroyed by feature creep.
If you’ve tried Element and thought “ah, slow Discord,” maybe have a scroll through matrix.org/ecosystem/clients/. I don’t want to get off topic but all my favorite software is standard/specification-based.
