That is the right attitude!

Really, I don't care. In the highly unlikely event I need to shoot at f22, I'll simply accept the hit I take in terms of diffraction. As it stands, I really need to go beyond f12 (anything beyond that is probably because I'm too lazy to buy an ND filter), and the effects are minimal enough for me.

Exactly the right attitude! Just keep in mind, of course, that deeper DOFs require more narrow apertures which means greater DOF, greater diffraction softening, and more noise for a given shutter speed.

When it matters depends greatly on the display size of the photo, the viewing distance, the visual acuity of the viewer, the other sources of blur in the photo, and the QT (quality threshold) of the viewer.
