Prior to the implementation of VPath, individual emote button lookups were O(1) time-complexity. With VPath, individual emote button lookups are now O(n) where n is the number of mounted base folders. This causes extreme amounts of file I/O and lag on loading large characters while using multiple mounted base folders. This is an unacceptable level of performance degradation for such a common interaction.
I already explored a solution to this in January which was shot down due to nebulous design considerations.
