Don't quote me on this but it (NFC) already seems to be 
convention. I don't know how many input methode there are that 
produce decomposed forms (NFD) with separate accent and how many 
of those decomposed letters are actually in circulation today 
outside documents explicitely talking about them. I wish I'd see 
some hard data on this.
Exceptions often named on the internet is Apple filesystem 
metadata and filenames and copy pasting from it using Mac Finder 
file manager. In theory anything can make them but in practice 
little does.
However if I copy paste an ö I see in the wild anywhere else, 
it's almost certainly precomposed (NFC).

I pasted some German Wikipedia articles in this converter to 
check I'm not talking bullshit and it told me they were already 
in NFC.
