This feature was first introduced to users with Android 10. It was introduced because it was the easiest way for developers to test new updates. And it's getting even better with further updates.
Recently Mishaal Rahman a retired Editor in Chief from the XDA forums tweeted about it.

According to him, DSU will be getting several brand-new features and improvements like a huge performance boost, a weighted progress indicator bar and support for system_ext and product images.
Recently, several commits have been made on AOSP Gerrit which indicates that Google is making efficiency improvements to DSU. Due to the increase in the pre-defined shared memory, installing a GSI through DSU will be considerably faster.
Google has increased the memory from 8kib to 64kib and its testing shows that installation time is being reduced to just 45 seconds from 2 minutes and 2 seconds.
Synopsis of the Gerrit Commit:
This modest adjustment 8KiB -> 64KiB significantly boosts the DSU
installation time:
* physical device: 2m34s -> 45s
* virtual device: 46s -> 30s
