@anon41901724: you did not mention the word “competition”, but using the 2 apps in the same argument means they are in effect competitors, like Obsidian and Roam, or Obsidian and Evernote, or Obsidian and etc. Apps operating in the same market segment are competitors, perhaps only partially so in certain cases.
As for what a lot of people want, I do not dispute it. Nevertheless, the devs decide on the features, and certainly on the priorities. And since we don’t know if and when “Alias” will become core, it seems to me that if there is someone who proposes to convert an existing something into a plug-in it would be more than welcome, esp. considering that many people, as you say, want/need it.
