The nix-mode package already does this and it shadows other entries for the .drv files in auto-mode-alist (namely Guix derivations).

featurep! will be renamed modulep! in the future, so it's been
deprecated. They have identical interfaces, and can be replaced without
issue.
featurep! was never quite the right name for this macro. It implied that
it had some connection to featurep, which it doesn't (only that it was
similar in purpose; still, Doom modules are not features). To undo such
implications and be consistent with its namespace (and since we're
heading into a storm of breaking changes with the v3 release anyway),
now was the best opportunity to begin the transition.
Moved add-hook calls (for tree-sitter initialization) into their
respective modes' config blocks, or nearby, to be consistent with how
other, similar tools (like lsp!) are initialized, and does so at
runtime, rather than at expansion/compile time, which eval-when! caused.
Calling this pivotal macro "def-package!" has frequently been a source
of confusion. It is a thin wrapper around use-package, and it should be
obvious that it is so. For this reason, and to match the naming
convention used with other convenience macros/wrappers, it is now
use-package!.
Also changes def-package-hook! -> use-package-hook!
The old macros are now marked obsolete and will be removed when straight
integration is merged.
+ Move set-company-backend! out of conditional (it is an autodef, meaning it will simply no-op if the company module is disabled)
+ Removed helm-nixos-options config, because `helm-nixos-options` is already autoloaded by the package
+ Simplify map! usage
+ Move nix-mode to the top, as it is the focal package of this module
Now that we are loading package autoloads files (as part of the
generated doom-package-autoload-file when running make autoloads), many
:commands properties are redundant. In fact, many def-package! blocks
are redundant.
In some cases, we can do without a config.el file entirely, and can move
into the autoloads file or rely entirely on package autoloads.
Also, many settings have been moved in their module's autoloads files,
which makes them available ASAP; their use no longer depends on module
load order.
This gained me a modest ~10% boost in startup speed.
