Does the existing pattern work here? All this code is solving the exact same problem, and what I hate about this version is that it looks like every public api change is going to need an entry here which is going to regularly shoot people's toes off.

I agree this is not optimal, but the checksum trick doesn't work for most of the entries I added because they're data only.

We could maybe use --whole-archive or codegen-units=1 to get around this approach entirely, but I haven't thought through all of the consequences with those approaches (We do codegen-units=1 for Release on Firefox, and it's a huge (in the 20x range) build time regression.

Hmm, I seem to have irreparably merged these unintentionally by trying to change the order...

I hate it but have no better ideas :)
