invisible universal variant and merger_must_run_binaries

Just wanted to point out a potential issue with the universal variant 

Let's assume a user on a BigSur Intel system wants to build some 
software +universal to support arm64.

One port needed +universal has some tricks in it, and requires 
"merger_must_run_binaries". That port cannot be built universal on an 
Intel system (which can't run arm64) but can be built universal on an 
arm64 system (which can run Intel). So let's say that universal port is 
built, and uploaded to the buildbot or similar.

Joe Schmoe on BigSur Intel could download and install that port 
+universal, and be on his way.

But now, his system will never see that port could be universal (because 
he can't built it universal), and the chain collapses, some would say 

So -- how to elegantly handle this issue, if possible?
