whats the state of `cmake_args`?

[Jan200101]

to quickly describe cmake_args (since documentation is poor on it):
its an extra parameter of the dependency method that allows specifying cmake arguments for cmake modules only (it will not be used for cmake subprojects)

Currently this parameter appears to be used by only 4 projects on github, has no test cases has no documentation besides a 1 line note on the dependencies page and an inclusion in the 0.50.0 release notes

Further more the function that parses the flag check_cmake_args has this TODO above it:

meson/mesonbuild/cmake/common.py

Line 133 in e542901

# TODO: this function will become obsolete once the `cmake_args` kwarg is dropped

and an invocation of it that includes this comment:

meson/mesonbuild/cmake/interpreter.py

Lines 826 to 827 in e542901

	# TODO: drop this check once the deprecated `cmake_args` kwarg is removed
	extra_cmake_options = check_cmake_args(extra_cmake_options)

I couldn't find anything that mentions the parameter being deprecated (besides the line itself) and there is no logging or version check in the code that announces its deprecation or prevents its use in newer meson projects

I saw this too when I was working on my PR to port the dependency() keyword arguments to the typed_kwargs framework. I coulnd't find much in git history about it either, so whatever the plan was it seems like it was in Daniel's head, and not recorded. I would be in favor of dropping the comment unless someone has a good plan for how/why it should be removed.
