The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.

While we do recognize the importance of platform security and user safety, the Android platform already includes multiple security mechanisms that do not require central registration. Forcibly injecting an alien security model that runs counter to Android’s historic open nature threatens innovation, competition, privacy, and user freedom. We urge Google to withdraw this policy and work with the open-source and security communities on less restrictive alternatives.
