Clinical trial of mRNA universal influenza vaccine candidate begins

Right but that varies from virus to virus - the goal of a universal flu vaccine is to hit a well-conserved region of the virus which doesn't mutate much. Our inability to do it so far doesn't necessarily imply it's impossible.

Whereas most current COVID vaccines target the spike, and disappointingly the spike is a lot more malleable then hoped.

It's a fairly solid indicator though that it must be tricky or that the body is making some tradeoff.

Or just that we can't stabilize/synthesize the protein usefully in a vaccine with existing techniques.

One of the big deals of mRNA is that because you get the proteins made in-vivo (in the body), you inherit all the body's machinery to do this naturally - after all, viral replication requires using that exact same machinery in order to replicate up the viral proteins in the first place.
