Yeah things like Okta are planned to be supported in the long term. Just need to prioritize the different integrations as there are so much tools I can still add support for. And every single integration presents its unique challenges, so these all take some time.
Yeah feel free to open a feature request on GitHub, that way I can keep track easier. You can also make my life much easier if you provide more details on how exactly such an integration could work. Because in practice, many requested integrations are for tools that I have never used before. I have to first figure them out myself and set up proper a testing environment. That part sometimes takes more time than implementing the actual integration itself because some tools are quite difficult to set up (Looking at you, goteleport).
