Empty repositories have no refs and upload-pack therefore does not
advertise capabilities for them:
$ GIT_TRACE_PACKET=1 git ls-remote file://$(pwd)/foo
11:54:22.279526 pkt-line.c:46 packet: upload-pack> 0000
11:54:22.279744 pkt-line.c:46 packet: git< 0000
11:54:22.279875 pkt-line.c:46 packet: git> 0000
11:54:22.279918 pkt-line.c:46 packet: upload-pack< 0000
Meanwhile receive-pack does advertise capabilities, guarded by a
capabilities^{} ref. And JGit based servers advertise capabilities
even in upload-pack, ever since https://git.eclipse.org/r/15253
11:54:52.028306 pkt-line.c:46 packet: git<
0000000000000000000000000000000000000000 capabilities^{}\0 include-tag

11:54:52.028444 pkt-line.c:46 packet: git> 0000
Nothing bad seems to have happened from that, so C git should presumably
follow suit (and filter out the fake 'capabilities^{}' ref on the client
side while at it).
