I don't think it's a waste :-)
I'd and I really go with modules, because it's clean:
options = {
# you options, like attrsOf str
};
config = {
systemd.services = ... # here you map your options (merged for you
already!) to systemd options.
};
And, apparently, existing modules already do merge for you:
