The only way I can get the indentation to work with matrix environments
like matrix, bmatrix, etc. is to start the line with \begin{matrix}. For
instance, putting:
Let $E = \begin{bmatrix}
1 & 0\\
0 & 1
\end{bmatrix}$ be the
identity matrix.
results in the indentation being offset for the remainder of the file.

The recipe provided in the other response should work, it is also
described here[1].

I suggest you take this comment to emacs-devel <at> gnu.org if you want to
discuss it seriously with the Emacs maintainers.

You can use LSP servers with Emacs through one of these clients:

 • https://github.com/joaotavora/eglot
 • https://github.com/emacs-lsp/lsp-mode

As always, this means that someone(™) has to do the job.  AUCTeX's
source code is available, if that someone wants to get an idea how it's
done in elisp.

I don't see we're discussing a bug, hence I'm closing this report.
Please feel free to re-open if a bug discussion will happen.

Best, Arash
