Good observation. Agreed.

I've never heard of js-json-mode until today. I always use json-mode 
(which AFAIK) is still the default for json-files, unless overridden in 
your own .emacs setup.

I can see that in Emacs git right now, json-ts-mode behaves closely to 
js-json-mode. I honestly expected it to match the Emacs-default 
json-mode though, and found the current highlighting ... somewhat 
unexpected.

IMO, yes the keys are technically speaking strings, but the are 
predominantly and semantically keys, and IMO should be highlighted as 
such. Just like json-mode does.

I realise this is somewhat subjective and preferential, but as far as my 
preference goes, I clearly prefer json-mode over js-json-mode, and as 
such also prefer the current patch-sets for json-ts-mode which Theo has 
submitted.

(On my part we can avoid side-tracking related to why there are multiple 
json-modes, unless has a deep need to contextualize these changes 
related to those ;) )
