The layout of stamp files ensures that changes to WORKDIR mean recipes get rebuilt correctly. Since WORKDIR usually contains MULTIMACH_TARGET_SYS and that depends on tune variables, including WORKDIR in sstate checksums adds a lot of noise to the system for what amounts to no gain.
On the other hand, removing it reduces noise, reduces the size of the siginfo files and reduces the amount of processing bitbake has to do. It therefore seems like dropping it from the checksums is an all around win.
