We can enable Dex layout reordering to use startup profiles. To use them, the benchmark build needs to have isMinifyEnabled = false.

Can you specify the issue more ...

+1 Can you explain what "Dex layout reordering" is? I found nothing while search for these terms. Is it an automated AGP process? Or a hidden configuration?

I guess it is DEX layout optimizations

Thanks a lot for the link. This means we need to enable this feature android.experimental.r8.dex-startup-optimization

android {
  experimentalProperties["android.experimental.r8.dex-startup-optimization"] = true
}

Thanks @priyanshnama. With already #1020 in flight to address this issue there is no need for another approach at this time.

The switch to not use a specific build type but rely on the Baseline Profile Gradle plugin to provide the right build type makes this bug obsolete.
