We might wind up needing to do the same thing here as we did with tailscale/tailsql#33, as we build it for deployment in the same way. We can patch this change and find out, but I suspect it will be the same situation.

That helps too. But I meant more the compatibility with the checked-in dependency. I patched your PR and did a build, and it does seem to work, though, so I think this is probably fine.
