This sounds like a reasonable option.

DFSan development is now fairly mature. We don't support other platforms due to lack of demand (all the users I'm aware of are x86_64).

As a side note: I am pleased to see that the patch required to add this support is as small as I'd expect (even if we add the pieces in D140689 <https://reviews.llvm.org/D140689> not shown here atm).
