Passing project into a plugin extension?

I am developing a plugin with an extension. I pass a project into this extension as a parameter, and use it to configure certain task when the extension’s methods are called.

Plugin code:

class MyPlugin : Plugin<Project> {
    override fun apply(target: Project): Unit = {
        extensions.create<MyPluginExtension>("exten", project)

Extension code:

open class MyPluginExtension @Inject constructor(val project: Project) {
    fun configureTasks() {
        project.tasks.named("blah") { ... }

Is this OK? Don’t I cause any memory leaks or something else stupid?
