Two quick comments:

I tend to agree, but have to acknowledge that there's a risk of putting
too much burden on end-users to select where to report their feedback,
when they may simply not know enough to make that determination.  Or at
least may not feel comfortable with it.
That's exactly why I think it's essential to have an easy possibility to move reports around as needed (i.e. let end-users try to make their best guess but without putting any pressure on them) and let more experienced folk sort out the reports which ended up in the wrong tracker.
Good example is GitLab itself: They have three trackers (GitLab EE, GitLab CE and gitlab.com) and I never now where to report anything, so I make my best guess and report away - until now almost always somebody moved the bug according to whatever internal guidelines they have (I have no idea what they are but I feel perfectly fine with not caring ;-) ).

Part of the argument of the two-layer approach would be to address this
by having a one-stop-shop inbox that is friendly and suitable for
non-technical users.  And then a second layer where the individual items
are broken out into more technically detailed repositories which are
sensibly grouped in ways that are more manageable for triagers and
developers.
Here I have to ask for a quick clarification:

As I assume we don't want four trackers
