For people still waiting on this PR to be merged, I created a workaround, Which involves creating a class extending UCropActivity and foloowing code:

• Add private var isReadyToFinish = true property
• Add private lateinit var loader: MenuItem property to reference the top right loader and initialize it in onCreateOptionsMenu()

  override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    val result = super.onCreateOptionsMenu(menu)
    loader = menu.findItem(R.id.menu_loader)!!
    return result
  }

• Also, there's a blocking view set, to get a reference:

  private lateinit var blockingView: View
  //...

  override fun onStart() {
  //...
  blockingView = ucrop_photobox.getChildAt(ucrop_photobox.childCount - 1)  // Last view in the layout
  // ucrop_photobox is a kotlin extension reference to the R.id.ucrop_photobox ViewGroup in the ucrop_activity_photobox.xml file
  // You can override that file if you can't find the reference.
  }

• Override setResultUri() function like this

  override fun setResultUri(uri: Uri?, resultAspectRatio: Float, offsetX: Int, offsetY: Int, imageWidth: Int, imageHeight: Int) {
    if (imageWidth in MIN_WIDTH .. MAX_WIDTH && imageHeight in MIN_HEIGHT .. MAX_HEIGHT) {
      isReadyToFinish = true
      super.setResultUri(uri, resultAspectRatio, offsetX, offsetY, imageWidth, imageHeight)
    } else {
      isReadyToFinish = false
      loader.isVisible = false
      blockingView.isClickable = false
      
      // Do whatever you want here, when the image dimensions are out of bounds
    }
  }

  override fun finish() {
    if (isReadyToFinish) {
      super.finish()
    }
  }```

I know it looks a little hack-ey but hey, it works for me!
