I see the same behavior in Emacs 29.1 and in Emacs 28.2, so I wonder
why you say this started only about a month ago.  Do you indeed see
that auto-fill-mode in a .el file does NOT produce two-space
indentation, under the default value of adaptive-fill-mode, when you
use Emacs 29.1 or older?

If this is not what you mean, can you explain what I missed in your
report?
