I see this issue a lot in plugins that use Roact, where the plugin has the tiniest functionality (like an icon pack menu) and the actual file is 90% roact modules which in this case is, essentially, bloat.
I understand why Roblox would want uniformity in their newer core UI, but I strongly believe using heavy frameworks like this is what’s causing delays for basic fixes, like the player list scrolling being buggy for over a year.
