It seems like it might make more sense to move all of the //blimp/client/dummy
code into this directory, and just
provide the two different definitions of :core so that it's a little clearer
that they're related, e.g.:

if (enable_blimp) {
  source_set("core") { ... }
} else {
  source_set("core") { ... }
}

If you do that, I think you can also just inline the declare_args() block into
this file and not need blimp.gni. Then your consumers can unconditionally depend
on //blimp/client/core and not worry about whether blimp is enabled or not;
we've generally found that this gives you better modularity in the build files.

All done! Thanks for your help!
