@Faizaan Merchant Greetings!
I understand your concern about the limitations of the classic deployment and the upcoming deprecation. Suggest you just perform Azure Site Recovery set up and do not use Migrate project. Enable replication for physical servers and perform a failover as detailed here -
This will use the modernize version instead of the classic been used in migrate. As you are already aware that the modernize appliance is much more up to date and supports more kernels than the classic.
Regarding your feedback about product limitations/functionalities, we have relayed the same to the product group. Appreciate if you could post this feedback here - https://feedback.azure.com/d365community/forum/cd45915f-0f25-ec11-b6e6-000d3a4f09d0 so that it will be tracked by the feature owners to consider it for feature enhancement.
Hope this helps. Let us know if you have any further questions!
