For our specific usage *RIGHT NOW*, sure. All that's *REALLY* required, for the Telescope's production-side is writing out those blocks, this is true... but doing it this way would be kneecapping myself in the sense of maintenance & usability. (Like global-variables/states.) [WRT software:] The Astronomy field is pretty fragmented and ripe for solid, reliable, libraries. Getting a good FITS library is only one of several things I'd like to produce: (1) A good ISO 8601 library, to include periods and intervals; --(a) This would include a secondary scheduling library. (2) A stellar-coordinate library; (3) A good abstraction for telescope-control.
