Hi Bruce,
Sorry for the late reply. Holiday time in Israel.

OK, all indentation will be with tab.

Yep it is not needed. Also from meson sources:
output = kwargs['output']
ofile_rpath = os.path.join(self.subdir, output)
if not isinstance(output, str):
raise InterpreterException('Output file name must be a string')
if ofile_rpath in self.configure_file_outputs:
mesonbuildfile = os.path.join(self.subdir, 'meson.build')
current_call = "{}:{}".format(mesonbuildfile, self.current_lineno)
first_call = "{}:{}".format(mesonbuildfile, self.configure_file_outputs[ofile_rpath])
mlog.warning('Output file', mlog.bold(ofile_rpath, True), 'for configure_file() at', current_call, 'o
verwrites configure_file() output at', first_call)

Done.

I don't understand the benefit with this change. Is there?

No problem to split.
Another change in plans:

I don't see the need to constantly update with each device being added.
