Glad to finally see 28th getting more traction, I was thinking about it just the other day. Personally, I'd love for EU to introduce more institutions that cut at member state sovereignty in favor of tighter integration. What comes to mind immediately is a 28th regime for employment and personal taxes, so companies don't have to resort to workarounds like employee of record or fake "contractors". It seems that EU late binds making big decisions until all options collapse, current events will probably result in more push for federalization overall.
