Registration can't be removed because there's still a usage in ClsFileImpl:

Fix an exception when kotlin resolve was invoked when searching
for tests while indexing (probably many other cases)
Does not actually fix the behaviour, the test will not be found
resulting in undesired behaviour
Full-blown infrastructure for resolving Kotlin in dumb mode is needed
to fix the behaviour
#KT-24979 Fixed
Introduce Gradle models for plugins 'kotlin-allopen', 'kotlin-noarg' and
'kotlin-sam-with-receiver'. Corresponding model builders are registered
in each one of those plugin main classes.
A Kapt model for Gradle projects including 'kotlin-kapt'plugin is
introduced. Its model builder KaptModelBuilder produces an
implementation of these models and can be queried through the Gradle
Tooling API when needed. Model builder is registered in
Kapt3GradleSubplugin.
A KotlinProject model for Gradle projects including Kotlin (JVM, JS or
common) plugins is introduced. Its model builder KotlinModelBuilder
produces an implementation of these models and can be queried through
the Gradle Tooling API when needed. Model builder is registered in the
corresponding Kotlin Gradle plugins.
Model definition should be published as a separate artifact in public
repositories so it can be consumed when needed.
