Graphical table creator? View and export ER schemas? SQL Syntax and autocomplete in .sql files AND within literal strings in your code? Query explainer?
Yeah, I don't think so.
Positron provides a batteries-included experience that lets you work with Python and R out of the box; it's easier to get started, everything's already set up for data work, and the tools all work together smoothly. At least, that's the goal. :-)
(disclaimer - I work on Positron)
Also, my impression is that that is also a big part of why MATLAB still exists, despite outraging prices.
I think the common theme among these tools' main user groups is that they are not developers. They are not comfortable fiddling a lot with a dev environment, but can be productive in an environment where everything just works.
Thus, if Positron can get the same smooth and rock-solid out-of-the box experience, it will be able to reach a lot of these non-developer user groups.
At least that's my 5c.
