It was asked by @CMCDragonkai to elaborate on that, so let's just do
this by actually providing a code comment.

The xrandrHeads option has been there since a long time, so there is no
need to advertise it as a new feature.
Instead, let's focus on just what has changed, which is that we now
assign one head to be primary.

Using invalid module options in the submodule isn't very nice, because
it doesn't give very useful errors in case of type mismatch, also we
don't get descriptions of these options as they're effecively
nonexistent to the module system. Another downside of this is that
merging of these options isn't done correctly as well (eg. for
types.lines).
So we now have proper submodules for each xrandrHead and we also use
corcedTo in the type of xrandrHeads so that we can populate the
submodule's "output" option in case a plain string is defined for a list
item.
Instead of silently skipping multiple primary heads, we now have an
assertion, which displays a message and aborts configuration evaluation
appropriately.

Split outputs mean that the "include" folder from PHP gets placed into a
"dev" derivation. However php-config is not aware of this, which means
that compiling extensions with phpize fails with an error about being
unable to find header files (see #24357, #24420). This fixes that by:
1. passing the `--includedir` flag to `configure` so that `php-config`
gives the correct paths.
2. moving the `phpize` and `php-config` scripts and man pages to the
dev derivation, to prevent cylic references.
3. ensuring that the `configure` script arguments are stripped from
all binaries, including `php-embed`, to prevent cyclic references.
In the wrapper scripts, both OCAMLPATH and CAML_LD_LIBRARY_PATH where
being created with a trailing literal $OCAMLPATH, rather than the
expanded version. Thus if, for example, ocamlPackages.core was present
in OCAMLPATH prior to running utop, the wrapper script would set the
variable to $utop_dependencies:'$OCAMLPATH', and when using utop to
open Core.Std, the following error was reported:
findlib: [WARNING] cannot read directory $OCAMLPATH: No such file
or directory
This patch fixes the quoting issue, and further refactors the build to
use standard wrapProgram helper, and uses an "inner derivation" to
re-use the setupHook machinery of buildOCaml and findlib instead of
manually specifying the OCAMLPATH required for utop along with
transitive dependencies.
This changes much of the make-disk-image.nix logic (and thus most NixOS
image building) to use LKL to set up the target directory structure rather
than a Linux VM. The only work we still do in a VM is less IO-heavy stuff
that while still time-consuming, is less of the overall load. The goal is
to kill more of that stuff, but that will require deeper changes to NixOS
activation scripts and switch-to-configuration.pl, and I don't want to
bite off too much at once.
