The exported VG checking/enforcement was scattered and inconsistent. This centralizes it and makes it consistent, following the existing approach for foreign and shared VGs/PVs, which are very similar to exported VGs/PVs. The access policy that now applies to foreign/shared/exported VGs/PVs, is that if a foreign/shared/exported VG/PV is named on the command line (i.e. explicitly requested by the user), and the command is not permitted to operate on it because it is foreign/shared/exported, then an access error is reported and the command exits with an error. But, if the command is processing all VGs/PVs, and happens to come across a foreign/shared/exported VG/PV (that is not explicitly named on the command line), then the command silently skips it and does not produce an error. A command using tags or --select handles inaccessible VGs/PVs the same way as a command processing all VGs/PVs, and will not report/return errors if these inaccessible VGs/PVs exist. The new policy fixes the exit codes on a somewhat random set of commands that previously exited with an error if they were looking at all VGs/PVs and an exported VG existed on the system. There should be no change to which commands are allowed/disallowed on exported VGs/PVs. Certain LV commands (lvs/lvdisplay/lvscan) would previously not display LVs from an exported VG (for unknown reasons). This has not changed. The lvm fullreport command would previously report info about an exported VG but not about the LVs in it. This has changed to include all info from the exported VG.
