> People just don't use this because they want to write "portable" "standard" C

Something that bothers me is the Venn diagram of people that think abstraction is slow and error prone and people that only write portable C.

How many C implementations do you actually need to compile against? I don't think I've seen more than 3 outside Unix software from the 90s. Using non portable extensions is in fact totally doable for your application and you should probably do it, and just duplicate/triplicate code where you have to. It's not that hard to write and not hard to read.
