I haven't checked the 12 factors for a while but feel proud to have worked on systems probably for a long old while where most or all have applied. To the point I'd naturally do these things without consciously thinking. I think that says a lot about good practices spreading than anything else. To not do these things: maybe a startup moving fast, or a very isolated company or just some old legacy COBOL type thing where you want the thing to still work as the main concern.
