Some server params - directoryperdb & wiredTigerDirectoryForIndexes - can inject path separators into ident names. The intended behavior on Windows is not currently known (at least to myself and colleagues in a Slack thread). Ident names are opaque to WT. So the question becomes should the server generate system-aware idents if a path separator must be included? Or should the ident names always be forward-slashes. Forward slashes in idents appears to pose challenges to the server and the storage engine if the platform doesn't support mixed-separator-style paths.

WT cannot handle backslashes in wiredtiger_open, so this presents a challenge to making the Windows-style paths in ident names.
