In QEMU we can't enable seccomp by default because its wide range of features means any default profile would be effectively useless. Libvirt knows that it uses a restricted set of QEMU features, so it can enable a more useful seccomp by default. I think swtpm won't have this complexity problem. Its functionality is relatively narrow & well understood & so it is practical to define a good seccomp profile & use that by default. So personally I'd merely provide an opt-out to turn it off unless you think this is likely to break something important.
