We plan to deprecate support of the window.PERSISTENT quota type in requestFileSystem().


Support for the PERSISTENT quota type contributes some amount of complexity to the quota system, but requestFileSystem() is the only consumer, with relatively low usage. Additionally, support for persistent quota will hinder work on storage partitioning, so it would be helpful to simplify the quota system prior to partitioning storage.
