Is there any "compatibility" type mode/option to use existing plugins with Ktor 2.0 or do they have to be migrated first?  Am currently using `KGraphQL` (<https://github.com/aPureBase/KGraphQL>) but get following when updating to use Ktor `2.0.0-beta-1`

```Type mismatch.
Required:
Plugin&lt;TypeVariable(P), TypeVariable(B), TypeVariable(F)&gt;
Found:
GraphQL.Feature```

I expect not, such a major version increment is a good moment to remove deprecated features from the codebase. I am using KGraphQL in my projects as well, however the maintainer seems to be AWOL since August/September, we might have to migrate to Graphql-Kotlin

They have to be migrated. You can try to solve your problem by renaming `ApplicationFeature` to `ApplicationPlugin` .
