If the EU has a common currency, why doesn't it have common bonds? Wouldn't this be beneficial to the EU?

A showerthought I had. I recall that the EU was issuing eurobonds for its NextGenEU project but that it would be a one-time thing. Which made me wonder why the EU hadn't done this before or why it's seemingly hesitant to make it a permanent thing. Wouldn't such a common bond be economically beneficial to a lot of member states? Especially poorer ones?

Imagine the logistics of such a thing:  who exactly gets the money, and who exactly is on the hook for paying it back?  What if Italy gets the money and doesn’t pay it back, does Germany step in to pay it to protect the credit-worthiness of the EU as a whole?  Why wouldn’t every EU country refuse to repay what it borrowed to make Germany (as an example) pay it off for them? 

Until the EU actually has a unified fiscal system, or at the very least an EU government with taxing authority reaching into the territories of all member states, you aren’t going to have the “EU” borrowing money.
