Which bit of this doesn't apply to *any* package requiring a niche 
toolchain component? It would be problematic for packages to 
gratuitously migrate to llvm, but packages that actually depend on its 
functionality are as welcome in the distribution as anything written in 
ADA, go, falcon, R, AGI, Pure, Q, any of the lisps or any other compiler 
or interpreter we ship.

Some of our toolchain components are much better supported than others, 
and obviously relying on one of the less supported ones is risky - 
unless anyone's willing to do the support work, it'll go away and so 
will all the packages that depend on it. Any maintainer is expected to 
understand that risk and make an appropriate and rational choice.
