I prefer not to shoot or use darks, flats or bias subs. With modern cameras it should not be a requirement.
I've no problem with that approach to imaging but I think it will limit your quality.
That is a compromise I can understand making since I really don't expect to ever start making exposures of 5+ minutes (could happen but I don't expect it) and that will limit the quality of what I do.
It is not actually a requirement that calibration images be used with even older-style cameras. With meticulous and skilled processing you could even get some really good images out of the MCU without calibration images - but it requires a lot more skill and time/labor.
But even the newer imaging rigs tend to benefit from calibration frames. The darks are less needed since the better CCD cameras have much of the amp-glow engineered out of them and the cooling is minimizing the hot/warm pixels - and the CMOS cameras generally need dithering in order to eliminate pattern noise. One can argue that the bias frames aren't that important, but they can make a difference.
The one that is more difficult to eliminate is the need for flats since that one generally isn't fixing camera issues but issues which are mostly associated with the optical train (vignetting, dust motes, etc.). But if you either use a sensor which is much smaller than the image circle or use cropping or other post-processing to work the vignetting - then if you keep your optics pristine the flats aren't all that required.
