Can we just put this change in the CL that implements it?

(I guess this helps enforce that it compiles in both variants, but it's also
important for mojo reviewers to review IPC changes in the actual context of the
change)

No problems. Since I have already found that the patch compiles in all the
trybots, I remove this part and only put it back in next CL.
