Description

Given the following config, straight will byte compile the package, and generate an autoload file. The autoload file pulls in rust-prog-mode unconditionally. I'm not sure how to workaround this, maybe wrap the file content with a runtime check?

(setq straight-use-package-by-default t)
(use-package rust-mode
  :init
  (setq rust-mode-treesitter-derive t))
$ cat rust-mode-autoloads.el
...
;;; Generated autoloads from rust-prog-mode.el

(register-definition-prefixes "rust-prog-mode" '("rust-"))
...

Research direction

Reproduce the configuration from the issue with rust-mode-treesitter-derive enabled, then inspect the generated rust-mode-autoloads.el and the rust-prog-mode.el autoload source. Check how straight's byte compilation and autoload generation produce the unconditional reference, and verify that the derived-mode setup no longer loads rust-prog-mode when it is unavailable.
