Can support kroki? (want feature)

[Kroki](https://kroki.io/) supports various formats.
Gitlab support kroki. ([Kroki diagrams | GitLab](https://docs.gitlab.com/ee/administration/integration/kroki.html))
I also use [Markdown Diagrams - Chrome Extension](https://chrome.google.com/webstore/detail/markdown-diagrams/pmoglnmodacnbbofbgcagndelmgaclel) when viewing on Github.

And run on docker. https://hub.docker.com/r/yuzutech/kroki
I want to use kroki as backend for plantuml, mermaind and others.
I replaced plantuml to kroki.
```vim
let g:mkdp_preview_options = { 'uml': { 'server': kroki_url } }
```

Is it possible to do everything else?
Or can it be replaced with one that assumes kroki?

like
```vim
let g:mkdp_kroki_server = 'https://kroki.com'
```
