deck gateway dump with RS256 JWT consumer secrets cannot be synced without modification

[ffjeremy]

This was discussed here previously.

The output of deck gateway dump leaves out the secret and makes it impossible to sync without modification.

Ideally, deck would not require secret at all for RS256 (and whatever others don't require it) so that dummy values are not required, and the diff/sync functionality works correctly.

EDIT: apologies for the edit. I was partially mistaken with my original issue description -- deck gateway diff and deck gateway sync do seem to correctly ignore the "dummy" secret so that it doesn't force an update.
