I know this will lead to a heated debate, but I have to agree with @Gargron.
Having to pick an instance/server is cited as the biggest hurdle to joining Mastodon, and dismissing people who feel this way is just plain rude.
Yes, the registration flow for Mastodon should be user-friendly. And yes, we need to live up to the promises of decentralized social media. We just need to get creative about our approach.

So the official App, has the optipn as default to join the main Mastodon instance, how easy would it be to make a patch so that each instance hosting the app, can patch, so that the app they offer defaults to that instance.
For example if I download the app from qoto, or follow a link from qoto, then it would download the patched version for that instance.
@zleap Ah, sorry, I wouldn't really know.
Maybe @fediversereport might have some insight?
