If you choose to map \System to $System, I'd suggest making the JMAP 
specification IANA considerations section register the four $System 
flags in the IMAP keyword registry as "names reserved for use by JMAP; 
use in IMAP not recommended". I'd also suggest renaming the registry to 
"IMAP/JMAP keywords" or "IMAP keywords and JMAP flags" (depending on 
terminology you want to use).
