 ### Maybe not required for MVP:
 - [ ] Consider enabling configuring ld-relay client context (aka goals endpoint): https://github.com/launchdarkly/ld-relay/blob/1adf0dde5b11343d3bdf011c86e3f7116c4960fc/internal/relayenv/js_context.go#L7
 - [ ] Terraform: validate variables (see TODOs in https://github.com/dorklyorg/terraform-aws-dorkly-flags/blob/main/variables.tf)
 - [ ] Terraform: Consider a command line tool to quickly create new flags and maybe turn them off in all envs
 - [ ] Terraform: Use freeform workflow with human input to create flags
 - [ ] Use localstack to do end to end testing (if possible)
-- [ ] Maybe never: Implement mobile key and client-side sdk setup (for now people should just use the client id)
 
 ### Pending DX tasks
 - [ ] temporary files and archives: keep them in memory avoiding weird filesystem bugs/flaky tests.
