That's a fairly persuasive argument; however, I suspect changing
ONLY_FOR/NOT_FOR/etc. to distinguish build from install is not
trivial. So maybe the best bet is to just allow installing compat
packages on their own system version; in theory it shouldn't do any

I don't think that's true; as things currently work, to cross-compile
you need to be able to install depends, so you need to have
bootstrapped with LOCALBASE and VARBASE (and so forth) pointing
somewhere that packages for the target can be installed. Which means
any package you can build, you can install.
