We've been adding features in left and right on demand and just haven't had time to optimize profile delivery yet since it hasn't been in high-demand, but that's next on our roadmap.
We're about to add in our one-click export to static, which will cut out all the existing Javascript on the page and optimize all assets before delivery, and then trigger re-builds on every change to your site. This will cut out the bloat you're seeing now.
TLDR: You're right, it's unnecessary. But we're actively fixing this! :)
