Turns out it is a lot more useful to (potentially) reuse the first stage than to carry a lot of additional weight to reuse the last stage.

Well, but the Shuttle SRBs were reusable.
The only non-reusable part was the external fuel tank.
But yeah, sending something as big as a bus up and down was probably the bane of it.
If you call rebuilding an engine every time reusable. SRBs and reusable do not go together at all.

But to use them again a lot of efforts had to be spent, comparing to what's possible with first stages of F9. That's why Shuttle boosters are called refurbishable.
