It's 2021, (almost 2022) and I'm pretty sure we could have a web version to manage the digest process of our MarketPlace package instead of using teams to say "hello this is my new package, see you in two month".
In fact, instead, we could have an upload part with visible comments from MarketPlace team as well as a flag status like "Ingest process step X: testing your package" blablabla and made some revisions to it.
Also, we will be able to make some translations fix (I just saw that 99% of the time, Microsoft translate is used (and it is not accurate at all in some languages) and add package fixes and have some better KPI too..
I'll be happy to create such a web tool and sell it to MS for some bitcoins :P
For Microsoft Team : They will be allow to see the critical fixes on some package that need to be pushed before the new package and they will be able to sort the priorities etc..
