Hi Thorsten,

Thanks for your reply.

Good to know, I'm new to the codebase so I'll keep that in mind.

Sure but there are occasions in the code where we are just modifying
a single coordinate. My recent patch is an example: <>

A single-component modifier isn't a must but it might be nice for
when we are only changing one coordinate.

If we do decide to go ahead with this I'll be sure to follow your
implementation requirements.

With many thanks,
