Hey @nicolas-morissette_6285,
Thanks for clarifying!
So it sounds like this is a non-critical integration point. In other words, you're not building a workflow that relies on the two to be integrally connected, it's more a "convenience" such that one team get another team's developer library packages more easily.
I'm more nervous about enabling / encouraging the first use case; given the velocity and unpredictability of ADO's changes, there's a high change it will "just break" some day -- and as you've seen from their support, it's hard to get "them" to care. We most definitely care, which is why I'm cautious about putting us in a position to be responsible for customers' infrastructure breaking on account of a third-party API suddenly changing.
We most definitely work with a lot of teams at Microsoft, but their internal org hasn't really changed in the many years since I first saw this...

... so a lot of times, it's partnering with customers to push different groups at Microsoft to work together to serve what should be their common interest (i.e. a paying customer). For example, getting AzureDevOps Packages and NuGet team to collaborate on API things.
After the change in guard at VSO/ADO(i.e. after Ed Blankenship), we really don't have any meaningful contacts or pull w/ that group. But we definitely have contacts and work closely with other teams (like NuGet team, etc).
All that said, we'll also work-around this quirk, and I've put in a change (PG-1862) to accommodate this. But just
