So I'm not totally convinced that treating an abrupt exit or EOF as an error is worth the hassle (others might disagree), but it's certainly reasonable.
Could you add a test for the new behavior?
something like

RUN: not clangd -run-synchronously < %s
<initialize and exit (no shutdown)>

RUN: not clangd -run-synchronously < %s
<initialize, and nothing else (stdin will just get eof)>
