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.
The layoffs come after a strong quarter for Block, with revenue, profit, and customer base all growing. But Dorsey appears to think that the rise of AI makes this move inevitable, presenting the decision as a choice between doing one sharp cut now, or laying people off slowly over a longer period of time.
